One bright morning rose on Trolberg, Vivi was snoring on her bed. She was taking a breather after going all that trouble to rescue Hilbert when he got captured by the Lost Clan. It wasn't before she felt some of the ground rumble. The girl yelped as she faceplanted on the floor. She grumbled as she went downstairs to get breakfast.

Vivi's mother was eating some yogurt. "Morning, sweetie. How was your day with that blue haired boy?"

"Oh, it was nothing I can't handle," Vivi brushed her fuzzy hair. "I even learned how to defend myself from bullies."

Vivi's father howled with pride. "Hoo! That's my girl!" He leaned forward and grabbed his girl, giving her a noogie.

The velvet red-haired kid was getting embarrassed. "Dad!" She tried to escape his grasp while the father laughed.

"Alright Vic, that's enough. Let her eat breakfast," Vivi's mom rolled her eyes as she finished her food. "Vivi needs to see Hilbert. They have another day of exploring to do."

"Makes sense to me, Nichole," Vic put down his daughter. "You go on have a great day with that boy, kid."

Vivi giggled as her father ruffled her hair. Upon finishing her waffles, brushing her teeth, and showering, the girl went off to meet up with Hilbert. She was unlucky to trip on the ground thanks to Trevor's goons, but she eventually reached Hilda's apartment. After entering, Vivi was confused by the lack of company here. Hilbert isn't even creating his inventions here. But she noticed Twig walking up to her. "Oh, you're such a cute little thing!"

Hilda entered the room as Twig was petted by Vivian. "Oh, hello Vivian. Looking for Hilbert? He strangely isn't here,"

"I find that odd. He usually would be in his room to make more creations. I don't think Spark would just keep waiting for him. Anyway, what are you doing?"

"Looking for Mum. Thought she would be back from her job," Hilda muttered. "I also got to help David with his singing audition. The last time he did one, he nearly set the area on fire due to his clumsiness."

Vivi stifled her laughter since she usually likes chaotic events occurring. Luckily the blue-haired girl didn't notice. "Maybe you should go to the hardware store to check up on her. She could use the company."

"Got it. Thanks, Vivi!" Hilda picked up Twig and headed out. "Don't forget to lock the door when you leave!"

As Vivi waved goodbye, she heard something hit the window. Upon further sight, it was the Raven. The bird started calling for his friend when Vivi opened the sliding glass door. "Helga! Zelda! Are you here?!"

"Calm down, Kentucky fried chicken, she just left," Vivi responded while rolling her eyes. "What are you doing here, anyway?"

"Came here to hide from some gangster kids. One nearly placed me in a fryer so they can have chicken nuggets," Raven shuddered at that thought. "Who are you, anyway? I wanted to thank her for trying to release me from that cage some hobo trapped me in."

"Well, you got Hilda confused with her brother. Can't blame you since they look alike," Vivi leaned against a couch. "You can call me Vivi. I'm friends mostly with Hilda's brother, but I'm good pals with Hilda as well."

The Raven sighed in relief. "Nice to see someone else is on my side. One more minute and I would have been Thanksgiving turkey,"

"Question, did you happen to see a blue-haired kid walk by while you were flying here?"

"Well, I saw the girl just leaving this area. Before that, I saw the kid that looks like her into some alley, being chased by some teenage girls." Raven picked up some chocolate and ate it.

"The Marra!" Vivi snapped her fingers as she started to head out. "You think you can help me look for Hilbert?"

"I guess so," Raven shrugged as he hopped on Vivi's head. "Just as long as I'm not put into a cage again."

"That's the least of your problems," Vivi exited the apartment as she locked the door. "If I were you, I'd avoid chefs working on the grill."

Back with Hilbert, he was getting bullied by the teenage girls. David's marra is among them. "Well, well, well, if it isn't my favorite bird nerd."

"Very mature, assholes," Hilbert muttered before another girl kicked him on the mud.

"Come on, this can't be the same girl you mentioned that tried to battle you, Shenzi," the girl with the ponytail said.

"I get that," David's Marra replied. "This is just her brother. It's no fun giving nightmares to someone that is already prepared for them. It sucks the fun of it."

"You got that right," the girl with glasses responded. "What should we do with this imbecile?"

"How about we wedgie him to a flagpole?" one other Marra suggested.

"Set his hair on fire?" Shenzi held up a lighter.

"Here's an idea: piss off, freaks!"

Everyone turned to see Vivi with the Raven. And boy, was she pissed.

"What the hell?" Shenzi was flabbergasted.

"Leave the boy alone." The red-haired girl hissed.

This was enough for the marra to stare at the girl before they burst into laughter. Shenzi even shed some tears from laughing too much.

"Or else what?" the girl with the glasses responded.

"Careful there, Emma. You don't want to be pushed by a sheep!" Shenzi taunted Vivi.

Suddenly, a water balloon hit her in the face. Her smile turned into a glare as Vivi smirked. "Baaaaa," She gloated while flipping her off. This could only end so well.

Eventually, Hilda was at the library checking for any solutions regarding David's dilemma and Johanna's job.

"You believe you can find out what you seek?" Alfur asked.

"There could be a chance," Hilda scurried to the other section of the library. "David's counting on me."

It was a matter of time before Twig went behind a bookcase and discovered a new area. His master followed and felt her jaw drop upon the new discovery.

"What the hell…" Hilda went downstairs and noticed several books everywhere. She was astonished with the sight but resumed her search to look for any leads on her task. She managed to find a book about tide mice. However, as she was reading it, she felt her arm being whacked. "OW!"

"What the hell do you think you're doing, you brat?" Hilda looked up to see that it was Kaisa. Boy, she wasn't happy to see her, let alone find out that Hilda trespassed here.

"Just checking on this book. Hope it's not too much trouble," the girl smiled innocently.

Kaisa rolled her eyes. "Ugh, whatever. Just remember this: these books are reference only. You can't rent them."

Hilda nodded as the librarian went back upstairs. She decided to copy the pages so her plan of helping David and Johanan can succeed.

"Hilda, make sure to get the footnote," Alfur warned her once the copy was made.

As Hilda was about to respond, she suddenly felt her head being pelted. "Ouch!" Upon further inspection, she realized that Trevor was taunting her with some rocks.

"Hey, witch! Your hair looks like a painted mop!"

Hilda growled in response. "You better not be harassing the bird!"

"Relax, I'm just here to give you it back." Trevor crossed his arms.

This changed Hilda's expression. "Really? That's odd of you, but okay. Bring it in."

Trevor held a straight face as he did what he was told. Hilda did not expect Trevor to display a certain finger. After a few seconds of silence, he began laughing. "Oh, man! You fell for it again! I never thought this would happen twice!"

This was enough for the blue-haired girl to be on a rage. "You asked for this, imbecile!"

While a fight was about to happen, Vivian and Hilbert were walking around Trolberg. They lost some teeth and have some messy hair due to the fight they had with the Marra.

"I never knew you can fight," Hilbert rubbed his eyes from the dirt he was shoved into minutes ago.

"What can I say?" Vivi shrugged. "I learned it from my pop. Why else did you think he looks muscular?"

"If anything, I assume your mom complained his finger was too small, so he gave her the whole fist." Hilbert smirked.

"Yeah…" Vivi soon caught on. "Hey!" She started punching Hilbert's shoulder, which didn't affect him in the slightest since he was trying too hard not to laugh.

They eventually bumped into David. "Hey, David."

"Oh, hi there Vivi and Hilbert," David looked around. "I can't believe we are gonna be on stage in three days. It's gonna be my big break!"

"More like a big wipeout," Hilbert muttered.

"Hey!" David took offense. "How was I supposed to know someone would be sent to the hospital that day?!"

"Moving on, you should probably head back home to practice," Vivi interrupted. "You don't want to get distracted from reaching your goal."

David's eyes widened. "Damn, you're right! I have to get going! See you later, guys!"

Hilbert caught on. "Hey, watch out for that-"

It was too late, as David eventually ran into a fire hydrant. The boy yelped in pain as he covered his crotch. "OW!"

Vivi and Hilbert inhaled sharply seeing their friend get harmed like that. It got worse when Hallgrim walked by David. Thinking he was a mugger, she pepper-sprayed David in the eyes and hit him with her purse. The two other kids winced as the pain resumed.

"We should probably walk him home before he gets killed out there," Vivi said nervously.

"Agreed,"

Back with Hilda, she was getting started on her Tide Mice task. She spat out a tooth since she was roughed up by Trevor. Eventually, she managed to create them.

"You sure you know what you are doing?" Alfur doubted that this was happening. "You should have checked the footnote."

"Footnote, smoothdope," Hilda rolled her eyes. "I know what I'm doing."

Alfur facepalmed as the brat created the tide mice. Carefully, she placed them on the respective victims including Johanna and David. She was lucky that none of them noticed a thing.

Several days later, the success of Hilda's targets had been ongoing. Johanna managed to get a different job and David is getting better by performing his solo. However, this doesn't mean that strange things weren't happening. Apart from Frida, nobody noticed that David started going through some changes. One day at school, he was creeping out Trevor everywhere. His eyes were purple, and he started making weird noises. Trevor tried to get away from him, but David kept following him like a ghost. They reached into a corner of the room.

"Get away from me, parasite!" Trevor cried as he tried hitting his stalker with a broom. This barely worked as David didn't feel a thing.

"David!" Frida cried as she rushed to her friend. While pulling him, she was unimpressed when Trevor flipped both kids off.

"Up yours, asshole!" Trevor cried.

Frida rolled her eyes as she dragged David back outside. Vivi noticed the commotion between the two kids but didn't have time to interact since she was focused on finding Hilbert. Strangely enough, the boy seemed strange as well. He was doing extra work for Hallgrim, cleaning up rooms and the floors, and washing windows. Vivi knew he would butter up to teachers, but not like this.

"Oh, hey Vivi. How have you been doing?" Hilbert noticed his friend approaching.

"Not as good as I expected," Vivi shrugged. "I noticed David stalking Trevor too much, so Frida had to pull him away. What are you doing, anyway?"

"Trying to get on Hallgrim's good side," Hilbert glanced around the room. "That hag is keeping an eye on Hilda, so I got to make sure she doesn't notice her shenanigans often."

"By being a kiss ass?" Vivi crossed her arms.

Hilbert laughed sarcastically. "Very funny. But you got to know that I'm trying to distract Hallgrim by getting her focus on me."

"Even though you hate your sister?"

Before the boy could respond, David started crawling around the ceiling. Frida kept trying to call him down, but it was no use. Hilbert knew there was nothing to lose, so he started hitting David with a broom to get him down. Eventually, the boy fell on Hilbert, and managed to get out of the trance. "Whoa. Hilbert? What are you doing here?"

Hilbert groaned as he got up. "You started acting like a creeper to Trevor in these past few weeks. Bad enough he has been crazy around birds, now he's gotta deal with you."

David got confused. "Why would I do things to him? He's a dick to Hilda, not to mention to you."

Hilbert raised an eyebrow. "Wait, you're not joking, right? You don't remember what you were doing earlier?"

"All I know is that I was eating some jorts until that Marra jerk came and threw a water balloon at me. That idiotic son of a—"

"Anyway, we should probably get going before Trevor uses his cigar on you," Frida pulled David away.

In the afternoon, Frida confronted Hilda regarding David's actions. Hilda covered her mouth, realizing her mistake. "Oh, crap."

This made Frida confused. "What?"

Alfur was cross. "I told you something was up when you didn't check the footnote! But did you listen? No!"

"I know, I know, I should have looked!" Hilda raised her hands in defense. "There must be an explanation for this. We got to get back to the library for solutions."

As everyone went to leave the apartment, they heard something shatter. The window was broken, with some glass on the floor. There was a brick with a note attached. It read 'Stop stalking me or I'm calling the cops. Signed with hate, Trevor.' Of course he would do a bonehead thing like this. Hilda rolled her eyes as she threw the brick outside. It ended up landing on Mr. Ostenfeld, causing him to have a concussion.

"Ouch," Frida winced. "Is he ok?"

"Eh, he's been worse. Come on, we need a solution to the mice!"

Once they reached the library, they discovered their problem. If Hilda does not banish the tide mice, some souls will be lost for good. The 30 days are up, and it must be done tonight—at the Warbler concert. Soon, the time came. All the Sparrow Scouts and their parents gather at the lodge for the performance. Even Johanna and Hilbert were there.

"I still can't believe you agreed on coming here," Johanna smiled. "Hilda was thrilled when she heard about it."

"Meh, might as well see this place crash and burn with David's clumsiness," the boy shrugged. "That boy will make destruction happen at the drop of a hat."

The raven leader welcomed everyone in the area. She introduced the grand finale: sparrow scouts forever. The curtain revealed Hilda and the other scouts. After a wave from Hilda, Johanna made some strange noises. Both blue-haired kids reacted in disgust when they saw their mom's actions.

"Oy, and they said Hallgrim was drunk," Hilbert muttered.

Soon, the kids began to sing. Everyone was in awe, especially David's parents. Soon, it became his moment.

"And now, it's David's solo!" the raven leader announced as David began his performance.

Everyone was in awe of David's solo. Hilbert even brought a camera to record it. What confused him was that Frida used the triangle to get Hilda's attention. The girl began chanting some words that made Hilbert think that she was drunk. The lights briefly went off as Hilda stopped chanting. A few moments later, some people started clapping before a lady pointed out that David had a mouse on his hair. The crowd got into a panic upon seeing that sight. Some ran into cliffs and jumped off them. It wasn't before Hilda ran to Johanna to hold onto some of the tide mice. David, Frida, Vivian, and Hilbert followed the others into their car.

"You did WHAT?!" Johanna yelled in shock.

"I'll explain when we get there!" Hilda dashed to the car. "Hurry, we are running out of time!"

The group went inside, and Hilda's mother slammed on the gas pedal. It was a rush hour for them. During the trip, Johanna and David started to make weird noises while purple fog came out of them. Hilda had to drive the car since her mom was unable to do so. Eventually, the three people she joined in making the noises.

Somewhere in the road, Trevor was walking by on the road. He was smoking a cigar, venting how his mom humiliated him in front of his friends for eating BBQ. "Idiot parent. She doesn't know who she is dealing with!"

Before he lit up his cigar again, he heard Johanna's car approaching at a high speed. Luckily, he was able to dodge it. Just as the boy whistled while walking, he eventually got hit by a driver.

"Out of the road, bozo!" the driver yelled.

Trevor responded by flipping him off. This was a poor action, as the driver backed up.
Some crunching can be heard.

Soon, the gang arrived at their destination. Hilda wasted no time doing the tasks to banish the tide mice. Eventually, Johanna and David were cured, but there was still some purple smoke surrounding them.

"What the hell?" Frida wondered.

"Where is that coming from?" David asked.

Hilda looked around to see where it was coming. She gasped when she realized where it was coming from. Apparently, Hilbert also had a tide mouse in his hair. Johanna managed to grab it after noticing it so she could hand it to her daughter. Hilbert was restored as the mouse was banished. Everyone was swept away as smoke cleared. The gang was covered in sand and seaweed.

"Hilda, I know you meant well," Johanna stated as she approached her daughter. "But what the hell were you thinking?!"

Hilda tried to explain as Hilbert slowly came to. He was dizzy from the whole adventure. "Do you have any idea what you put us through?!"

"This is exactly why I said its important to check the footnote!" Alfur scolded the blue haired girl.

"I was only trying to help…"

Hilbert grunted. "Well, don't offer more help. That didn't work out the last time, did it?"

"I was just making it up to you!"

Johanna sighed as she grabbed Hilbert and cleaned him up. "You two seriously need to stop getting at each other's necks, it is getting old."

"Yeah, it's not 'mice' to kill each other. Hahahaha! Get it?" Vivi chuckled.

She was met with angry glares from her peers. Frida flipped off Vivian as David shook his head in disapproval. Even Hilbert groaned hearing that pun.

"What? What?" Vivi asked in a dumbfounded manner.

"Too soon, Vivi. Too soon," Hilbert shook his head as he walked back home.

Johanna kneeled to her daughter. "Don't worry about it, Hilda. We know you were trying to give us a lucky break. You just need to be more careful, that's all."

"Lucky break, MY ASS!" the boy's voice was heard as he kept walking.

Johanna sighed as she cleaned up David. "Come on, let's go back home. We should hurry so we won't get drenched by the rain."

Everyone went back to their homes, unaware of some mice that climbed onto Hilda.
