I made an OC in the story previous to this one that I particularly liked but couldn't find an opportunity to insert her in, until now. See if you can spot what I originally intended for her character to be related to based on description alone. Enjoy the episode people.

Marco woke up a bit groggier than usual for some reason and rolled out of bed to get dressed thinking he could shower in the evening today. As he got on some of his clothes though he found he was having trouble doing so as something didn't quite feel right as he would put it. Shaking his head to clear it up of any grogginess he looked down at his hand to try and get a feel for the world around him only to come fully awake upon looking at it. His hand had three fingers on it and his skin was a green color now that he recognized from somewhere. Blinking in shock Marco stumbled to the door to his room only to trip upon opening it and fell down a water slide.

"AHHHHH!" Marco slid down the slide for a ways with it twisting and turning all different directions until Marco began to enjoy it. "WHOOOOO! Kalabunga!" Marco slid a little ways further until he finally fell into a pool at the bottom of the slide coming up after a few seconds spurting water. "Totally righteous dude! Wait, why did I say that? I don't speak like that." As he treaded water Star came up to the side wearing a turquoise swimsuit body wrap of some kind with her hair pulled under a silver swim cap.

"Oh I just wanted to surprise you for a change, in more ways than one." Star poofed up a full body mirror with her wand allowing Marco to take a good look at himself.

"I'm a… ninja turtle?!" Marco had in fact turned into one of the teenage mutant ninja turtles with the shell, the green skin, the three fingers, and even had a head shaped like theirs; though he still had his mole. "Cool, I'm the fifth ninja turtle Verrocchio! I hope my parents don't flip when they see this."

"Oh we are flipping alright." Raphael flipped into the pool splashing everyone. "I love this set up, it is a perfect get away without actually getting away." Angie flipped into the pool next and came up spurting water like a fountain.

"It's nice to see you use your wand so boldly Star; we hope for more surprises in the future." Star smiled blushing slightly as Ange and Raphael swam off. Marco got out of the water to talk to Star with his feet making a squelching sound.

"They are right Star, being bold like that is awesome. But a little warning next time because well…" He held up one of his feet showing it had a sock on it. "…wet socks are a form of torture in some countries." Star nodded her excitement not lessened in the least.

"I know, we actually use that form of torture. *ding dong* I'll get it!" Star leapt off waving her arms as she got to the door opening it. "Oh hey aunt Hel- *gasp* AUNT HELSINKI!" Star shrieked in glee leaping out of the door grabbing onto someone outside. Marco and his parents looked up to hear a female cockney style accent coming from outside.

"No need to get yourself in a bend over this, it's only your auntie." Star stepped back inside leading a woman who Marco swore could have stepped right out of a steampunk convention.

She was wearing practical clothing like that a mechanic might wear with what seemed to be a tool belt holding a bundle on her back hips that he was pretty sure held more tools. What made it unusual was that some of the tools were weird bronze and glass contraptions, she had leather boots that went all the way up to her knees, and she had on this strange studded leather corset of sorts. She also had on some sort of goggles resting on her forehead with some strange bronze and glass attachments to it that just screamed steampunk. The clothes also seemed a bit more tightly fitted then Marco thought those clothes should be fitted with the results showing off her athletic yet curvaceous figure… 'You know I think I have a thing for Butterfly milfs.' Marco thought to himself as he smacked his hand mentally for thinking about someone other then Jackie. She had shoulder length graying-blond hair done up in a ponytail, had stormy grey eyes, a grey clover mark on each cheek, appeared to be in her late 30's/early 40's, and also seemed to be missing a tooth in her smile. She looked around the inside smiling as she admired the work done with the place.

"I see you've been mastering your wand dear, well done." She rubbed Star's head with Star smiling and blushing pushing into Helsinki's hand. "So where are these Diaz's I've eard so much about from you?" Raphael and Angie came up out of the water with Marco walking over to greet Helsinki. "Ah you must Angie and Raphael, nice to meet you." She grabbed the duo in a hug which they returned eagerly. "Now where is this Marco I've eard of so much?" Everyone pointed at Marco with Helsinki double taking looking him up and down. "That's your son, looks like one of those new style warrior druids that ave been coming out recently." Star immediately waved her wand changing Marco back into his normal form while replying.

"Sorry, he always wanted to be a ninja turtle is all." Helsinki looked at Marco who was only now realizing he was shirtless and tried covering himself up. Helsinki gave him a big grin and came over scooping him up in hug as well.

"You I've eard so much about from Moon an Toffee about how you take care of their girl. And you're a cutie to top it off." She stepped back running her eyes over him with Marco blushing under her gaze. "So, ow far have you gone with Star me boy?" Marco blushed even more profusely with Angie and Raphael laughing at this and Star replying for him.

"He already has a girlfriend, a girl named Jackie at school." Helsinki chuckled at that turning back to Marco speaking to him.

"That's understandable." Marco finally realized something no one else had thought of and asked Helsinki a question.

"Who are you specifically?" She smiled and struck a slight pose.

"I am Helsinki Greyjoy; cousin to Moon Butterfly, Master of Engineering of the kingdom of Mewni, as well as Star's auntie an one of er tutors." Star smiled with Angie and Raphael clapping in awe but Marco still had one more question.

"Why are you here anyways, don't you have a lot of work back home?" Helsinki blinked for a second before speaking.

"Well I was around so I… oh who am I kidding; your parents banished me from the castle Star." The Diaz family gasped in shock but saw Star give her a deadpan look before talking.

"What did you do this time?" Helsinki shrugged her shoulders looking genuinely confused.

"Nothin as far as I could tell, they didn't even tell me what I did wrong specifically; just some vague complaints about being too loud and destructive. I keep all my work in the workshop and my noise is manageable; unlike Moon and Toffee when they have a "night of fun". Sometimes you can't sleep because of Moon's cries of pleasure echoing throughout the castle."

"That was bit too much information." Marco spoke as Star hid her face groaning slightly as Helsinki turned back to him smiling devilishly.

"Oh come on, you don't onestly think that old folks don't have se-"

"Please stop!" Star spoke moaning into her hands as Angie and Raphael laughed at this with Raphael speaking.

"She is right you know kids, we too have sex quite frequently." Marco and Star hid their faces as if trying to force those words from their minds. "So are you staying around for a day or two for things to blow over?" Helsinki nodded as Raphael and Angie smiled. "Excellent, that will allow me and the wifey to actually be "getting away" for a little while." The two turned and ran off eager to pack their bags as Helsinki laughed feeling a batting from around her feet.

"Ello there?" She looked down to see blue kitty and the three laser puppies batting around her feet. "You look like an interesting one indeed." She reached down and picked up kitty who gave her a dead pan look as she held her up. "Did Star make you wit her magic huh. You're a lovely fellow indeed." She held the cat close petting it slowly with the cat giving a resigned look. "An the puppies are cuties as well." Lasers came from one of the puppies eyes zapping her forehead making Helsinki blink in shock with a grin splitting her face. "Now that's what I like to see my girl. Care to show me around?" Star looked at her eager to move on from the previous conversation.

"Sure, a grand tour of the Diaz residence. Keep in mind this is the type of house most people in this land have." Helsinki laughed as Marco looked down at his one wet sock speaking in a resigned fashion.

"Now I need to get this off before school, it's like walking through abrasive pudding." Marco stared angrily at his sock as kitty came up after detaching itself from Helsinki and began pulling on the sock. "I think we need something stronger then…" Kitty then sliced at the sock cutting it up allowing it to come off. "…well that works, now I can use that one loose sock to make up for this one." Marco ran up the stairs to get ready for school with the puppies and kitty following him.


"And this is the bathroom, you go boom boom in there." Star pointed at the toilet with Helsinki going over and looking at it in wonder before speaking.

"Ow do they get the water all the way up ere without magic?" Star smiled explaining things to her.

"They use pumps and a massive system of underground water transportation pipes that would make your plan for the capitol look like child's play." Helsinki smiled at that almost shaking with excitement.

"The technology of this world is AMAZING! I need to study this water system and this "Toilet". Do you know how much more sanitary it would be and how much space could be saved on outhouses if it was made for the average person?" Star nodded with Helsinki smiling eagerly with a gleam in her eyes as Marco called up.

"Star, we need to get ready for school." Star shook her head began leaving while calling to her aunt.

"I'll be back later today auntie, don't burn the house down."

"No promises sweetie." As Star and Marco left Helsinki turned back to the toilet getting out her tool kit from the bundle on her back. "Now, time for me to pry open your secrets mistah Toilet."


Marco was staring at the board in a bored manner, 'hehe, nice' he thought to himself, as he scribbled something in his notebook he was not sure of but frankly didn't care enough to double check. He glanced over at Star who was diligently scribbling down notes and double checking the board looking kind of dorky in the process. He chuckled to himself a little remembering how Star got a A++ in Miss Skullnick's class and questioned how that was even possible in the first place given what the teacher was like. 'Well she is rather smart and gives everything she's got when it comes to studies so I guess it makes sense.' Marco thought as he was snapped out of his musing by some sort of muffled explosion. As he looked around in confusion the principle's voice came over the speaker system.

"There has been an explosion in the crafting shop area, please go to the designated fire drill…" Marco didn't catch the rest of it however as kids rushed to the door whooping with Ms. Skullnick staring at the chaos dead pan.

"Six years of middle school teacher education; for this." She got up and followed the students squeezing her troll frame through the door to try and gather up the kids. Marco and Star followed their teacher outside only for Star to suddenly catch her eye on something and run for it.

"Star serio… dang it." Marco chased after Star who was running for the disaster zone.

When they got there Marco saw to his shock a group of kids cheering on Helsinki as she seemed to be putting out the fire with some sort of scrapped together fire hose. As she did that Marco also saw Star kneeling over some girl who was coughing from something and rushed over to see what was going on. The girl was wearing an oversized grey hoodie and tan cargo shorts with glasses and appeared to be Asian with black ragged hair about half an inch to two inches long or so, had some slight acne and pock marks, and was carrying some sort of drawing book. She looked up as Marco approached and moved away from him slightly with Marco trying to calm her down.

"Shhh sh it's ok, everything is fine now. Star, what did your aunt do?" Star looked at Marco a bit nervous rubbing her tail.

"I don't know, but whatever it was it's not good." She turned back to the girl still on the ground looking like she wanted to get away from them both. "What's your name?" The girl looked at them nervously before answering with a slight Chinese accent.

"C-Chloe Park." Star smiled and pointed her wand at Chloe who moved away a little.

"Don't worry, I'm just gonna get all the smoke out of your lungs." With a slight shot from her wand Star got Chloe to give a mighty cough and forced out single cough of dense black smoke before she stopped coughing. "See, no problem. Now if you excuse us we need to see to someone else." Marco and Star took off while Chloe got up and moved away with her head down.

"And that's ow you clean up after yourself." Helsinki turned to the group of onlookers who began cheering for her as Star and Marco forced their way to the front. "Oh Star, ere to see the action? Well you're a bit late all things considered." Star came up a bit nervously before speaking.

"Um, can I talk to you for a moment?" Helsinki blinked in confusion until she understood and answered smiling.

"Of course luv. People, I'm sure you ave met Star right?" Everyone nodded with a few even giving Star the fist to chest and peace sign. "Well she is my niece and single for that matter, she is quite a catch being a princess and all." Star began blushing and rubbing her tail as people chuckled amongst themselves nodding in consent. "Well I ope to see you all soon enough. Cheers luvs." She walked off with everyone cheering after her as she and Star rounded a corner with Marco in tow. As they stopped Helsinki's voice got serious, "I went to far advertising you to people didn't I?" Star fixed her with a solid stare that answered her question. "Thought so." Star spoke up to her now.

"What happened in the workshop area?" Helsinki scoffed at Star's words before answering.

"That there is a workshop? That's no workshop, just a place for children to toy around in and learn the most rudimentary of basics. It can't even survive a single explosion." Marco got nervous at that looking to Star who looked a bit tired at this point before speaking.

"Ummm, I don't know what goes on in your workshop but this is earth and things function differently here than on Mewni." Helsinki blinked at his words and thwacked her head in annoyance before speaking.

"Bugger me sideways I forgot the translation thing between different worlds. I'm sorry Star my dear, I won't be taking my work out of the house again." They both smiled at Helsniki as she continued. "After all I finally found out the secret of the private toilet. I ad to replace it as I couldn't figure out how to put it back together again for some reason." Star and Marco both began sweating slightly looking at each other nervously.


Marco was walking home with Jackie chuckling over nothing specific when they heard what sounded to be a muted botsun whistle. Blinking in confusion they turned the corner to Marco's house to see steam coming out of some windows and some other indistinguishable muted noises coming from the house. Marco face-palmed at this and ran towards the house with Jackie following out of reflex coming to the door and opening it to get a small blast of steam. Inside the noise of gears turning around and combustion engines working could be heard as well as clashes of steel that Marco recognized were weapons. Moving through the house he got to the backyard, Jackie still in tow, to see Star with a poll ax and Helsinki with twin short swords with brass knuckles of a sort fighting in the backyard. As they watched Star pole vaulted with the bottom end of the poll ax and leapt into the air doing a wide swing with Helsinki ducking and rolling under it. She slammed upwards into Star throwing her off course and forced Star to drop the poll ax but was able to regain her footing facing down Helsinki with both of them smiling.

"What did I say about doing fancy moves girl?" Star chuckled as she ducked and rolled picking up the poll ax before facing Helsinki again and speaking.

"Only do it if there are no other options or if it is for fun; like what we are having now right?" Helsinki chuckled and replied.

"Of course luv, now shall we continue for the audience?" She gestured to Marco and Jackie with Star waving at them.

"Helsinki is just seeing if I'm up to snuff so to speak, nothing wrong here." Jackie chuckled with Marco looking in confusion until something dropped out of the sky and covered his eyes. Reaching up in confusion Marco pulled off the covering only to go beet red upon seeing that he had pulled off the bra of a well-endowed person. As he stared in shock at it Helsinki came up and took it from him chuckling at him.

"My my my, you ave a girlfriend and you still can't keep your ands of an older woman's undergarments. What to do with a boy like you?" She smiled with Jackie and Star giggling at Marco's expense as he shook off what had happened as best as possible before speaking.

"How did that get here? I mean bras don't just fall from the sky right?" The trio of women continued to giggle with Star inserting a comment.

"I'm sure some guys would love that though, especially with someone as well-endowed as you auntie?" Helsinki laughed very loudly at that turning back to Marco smiling sweetly as she pinched his cheek.

"Don't be upset me boy, we were just aving a little fun at my accident. You see, I kind of blew up the washing machine trying to do my laundry as I didn't ave the chance to do it before getting thrown out. So expect random clothes to appear at the strangest of places an times; an don't worry, I was able to repair that one." Marco shivered again in worry as Helsinki turned towards Jackie smiling. "Who might you be my girl? Marco's girl I've eard about?" Jackie nodded smiling with Helsinki smiling broadly at that. "Well you got yourself a good boy that's for sure. An what's that by your side?" Jackie held up her skateboard to Helsinki smiling before replying.

"This is a skateboard, many cool kids use these all the time to just move around." Helsinki looked at it intrigued before asking Jackie a question.

"Can you show me how it works?" Jackie chuckled while smiling and led Helsinki away to get educated on the skateboard. As she did so Star came up to Marco smiling at him and speaking with a big smile on her face.

"Isn't she great Marco, Helsinki is the cool aunt every kid wants as far as I can tell." Marco looked up at Star hiding his annoyance and smiled at Star who was positively beaming at him before replying.

"Yeah, she is pretty awesome; but I do hope she goes back home soon as I am not sure the house will be standing for much longer." Marco walked into the kitchen to see some sort of Dr. Seuss like invention that seemed to be making pancakes. As Marco stared at it for a second one of the unfinished pancakes was flipped and it flew through the air hitting Marco square in the face leaving a splatter of pancake batter all over him. "And what's more, I'm not sure how long I will be standing if this keeps up."


Marco woke up groaning due to it being too warm for him to sleep again. As Marco tossed around a little he realized it felt even hotter than it should be and also heard some rather loud noises coming from Star's room. As he got up shirtless and opened the door he was met with a blast of smoky air that made him cough as he walked out. Following the trail of smoky air he got to Star's room and opened the door to meet with a wave of heat and more smoke as he saw some sort of steam engine running full blast. Coughing a little bit he waved aside the smoke to see Helsinki and Star, the latter wearing some sort of engineers outfit as well, working on getting that engine to work properly in making… something that looked like a square tin can with the pull away cover on the top that you would find anchovies in. As he looked on in shock the two noticed him with Star calling down to him.

"So, what do you think? Helsinki's latest invention in making mass produced sealed containers to make non-perishable food stuffs." Marco stared in awe and annoyance as Helsinki followed up on Star's words.

"So much food that is produced tends to rot away after a year or two even if you preserve it properly. But with this we can keep food safe for decades if we keep it in a cool environment; we don't even ave to worry about moisture with these." Marco stared on before yelling up at them as he was not sure if they would have heard him if he had talked normally.

"Why are doing this in the middle of the night?" He was met with laughter as Helsinki responded.

"When you get an idea, you see it through to the bitter end and get on it before you lose motivation and inspiration. I do this all the time." She then turned back and tightened a few bolts with Star coming down to see Marco speaking to him.

"Do you wanna join in with us Marco, once you put on a shirt." Star giggled as Marco covered himself, 'Not sure why he does that, he's a guy.' Star thought. Marco was about to retort but he saw the happiness in Star's eyes and hesitated thinking back on the times when he saw her this happy. He then shook his head and smiled at Star speaking to her.

"I was just woken up by the heat this thing was making is all, I'll just open a window and go back to bed; see you in the morning." Marco waved turning away and closing the door behind him with Star looking on concerned confusion before she heard a pop from the machine.

"Bloody fukin bugger; Star get me some more bubblegum!"
