Hello, folks! Sorry for the late update, I was in a 'Digital' fase, but here is the true fourth chapter! I hope you all will like! And again, sorry for the late update

Here's the key:

"hello" = talking

"hello" = thinking

We were just... = Flashback

'I say...' = Thinking in flashback

"Hello" = talk in flashback

Be warned that the key may change through the story or for specific chapters, so I highly recommend to read the key of every chapter

Now, please enjoy the chapter

Plumber between Ninjas, chapter 4º: The first Mutagen threat! Beware the Squirrels!

I was in bed, still thinking about what happened yesterday

"I should have done more... I could have done more..." I keep repeating it over and over every time I remember how April reacted about her father's mutation

"I know I shouldn't be moping about something that was an accident... but I can't stop blaming myself!" I mentally shout to myself, and I would have keep doing it if a beeping sound had not interrupted me

I looked around to the hacking system, but it wasn't showing anything

"It's not from there... where is it?" I thought, just as a yellow light hit my eyes "What-" Then I finally get it

"The Ultimatrix..." I look closely the gauntlet and sure enough it was issuing a yellow light from the dial

"What is happening this time?" I asked to no one in particular

Just, please God, don't tell me something has broken in the Ultimatrix! I didn't do a thing this time and I'm in no mood to deal with a universal catastrophe!

But all that happened was the glow to get more potent "What is it?!" I though before closing my eyes because of the flash of yellow

A second later the flash died down and what I happened after that is something that I didn't believe

"Take the right!" Donna's voice broke the silence of the night "NO! TAKE THE LEFT! LEFT!"

The turtles are currently inside the T-Truck, that is almost crashing into buildings, however, the trash cans and everything in the sidewalk, excepts for post, was being destroyed by the personalized automobile

Inside the trunk, the turtles almost fell down because of the sudden change of course, lucky, they were using the safety bells

"Donna, maybe you can tell me before we go to the street?" Leona asked sarcastically

"I'm sorry, Leona" Donna apologise "There so many canister out there that my tracker is having problems zeroing a single reading-" Said tracker started to beep "TURN RIGHT!" She shouted, making Leona turn to said direction roughly, almost making every turtle fell from their sits

"Wow!" Raph complained "I think I just got shelless!"

"AAAAAAAAHHHHHHH" A scream came out of the blue, surprising Raph and Leona and making Donna almost let the tracker fall

The three turtles girls looked at the one who screamed: the orange masked one, who was reading a comic while seating in fetal position and trembling and holding a comic book in her hands

"Er, Miky, minding stop reading your comic and pay attention to the mission?" Leona asked her younger sister, who was still too frightened to talk

So Raph did what she does: she took the comic from Miky's hand...

"Hey! That comic is in perfect-" Raph slammed the comic in her face "-Near perfect condition, don't mess this up..." She finished a little dizzy in the head

Raph looked at the comic, it read 'Tale from the Cosmos', with an image of a woman being hold by an alien, that was ready to eat her

"Great! Another horror story! Guess who is gonna stay up all night in fright!" She sarcastically asked Miky

"Hey!" Micky pouted "I wasn't up all night because of fright! I was... hurm" She thought a little "Polishing my shell! That's it, polishing my shell!"

Raph would have hit her again, but Donna "LEFT!" Shout made the van turn

"STOP!" The purple masked turtle screamed. When the van stopped at a corner, Donna get out first wearing strange glasses, seeing what she is seeing, it is revealed that these glasses can find Mutagen

"I'm detecting Mutagen here, this way!" She said, leading her sisters with a detector of metal look alike, with Miky still reading her comic

The turtles followed the trail, until they heard something

The four quickly hide and waited for the person the leave

That is until a familiar silhouette with a glowing green gauntlet passed by

"Finally! I found one!" Ben exclaimed

"BEN!" Miky and Donna's shouted startle the poor boy as said turtles landed in front of him

After calming down a little, Ben greeted them "Hey, Donna, Miky! How's it going?" He asked them, but before one of them could ask

"WHAT WERE YOU THINKING?!" Rafh and surprising Leona's angry voice scared Donna and Miky

Rafh and Leona landed in front of their sisters and Ben. The first went straight to her sister "WHAT KIND OF NINJA ARE YOU?!" Then she looked at Ben "AND WHAT ARE YOU DOING HERE?!"

Ben smiled weakly "The same thing as you: searching for Mutagen"

Donna was surprised by that "But how did you knew there was one here?"

The alien boy laughed a little "Well, that's a story... You see-" A scream interrupted Ben's tale

The alien boy and the turtles ran towards the source, that was a closed Cinema, and found a homeless guy trying to get away from a... squirrel?

"Why is the guy afraid of a cute and harmless squirrel?" Rafh asked

The squirrel looked at the hero and heroines and roared at them with a three way mouth and a ugly tongue

"AAAHHHHAHHAH" The turtles girls screamed, jumped and hugged a neutral faced Ben, thus making Ben gain a huge blush on his face

The squirrel then ran to the homeless and... entered/invaded his mouth and then the guy was out cold

A moment of silence remained until Miky's frightened voice asked

"Now can I scream in fright?"

"Now can I breathe?" Ben suffocated voice asked, which made the girls to finally take note of the position they were in

Four turtles mutant girls hugging an Alien hero boy, tight

And his head was being pressed against their breast

.

.

.

"AAHAAAAHAHAAAAAAAHHHHAAAAHAAAAAAAAAAAAHHHHHHH!" The four girls screamed with a totally crimson face, totally overcoming their green, and Ben's face is the same way

The girls jumped away from Ben and went inside their shell, landing on the floor

"Man! I wish I could do that..." Ben thought while facing the sky, red faced while forgetting about one transformation that could do that...

"We-we-well" Leona's voice could be heard from inside her shell "Donna! Get the van ready!" Donna got out of her shell and ran to the van with an embarrassed face and in an unbelievable speed for a mutant turtle "Raph and Miky! Take the squirrel breath to the van!" The two said turtle did as they were told with the same crimson face and speed of Donna "See you later, Ben!" Leona ran to the van in the same speed as her sisters

Ben stayed there with his mouth hanging and a stunned expression when what happened finally sink in on his mind "WAIT!" The van ran away "Aaaaannnnnnnddddd they're gone already..." Ben said while sighed with his head hanging down

Turtles Girls P.O.V.

The four sisters finally arrived to their lair, in silence just like the trip back. They still are too embarrassed to talk after the... hug

They are trying to not alert their sensei of their little visit

"Okay..." Leona whispered looked to her sisters "Stay quiet that we do not want to alert Sensei..."

"Alert me of what?" A mature and musical voice asked, scaring the girls senseless. Leona looked behind her to see a female humanoid rat. She has a voluptuous figure with D-cup breast and wide hips. She has little whiskers and was wearing a purple kimono with pink flowers on the left arm, she also has a tail and her hair fur was tied in a short pony tail. She is Yamako Hioshi, the Mistress Splinter and Sensei of the Turtle Ninjas "Maybe tell me what you are doing?" She asked in a suppressed angry voice

Leona got paralyzed "Sensei! Haha! We have a funny story to explain all of this!" She tried to defend while her sister dragged the man

"Well, I hope so, because I want to know why you all brought here a strange to our supposedly secret lair!" She shouted

"He he he..." Leona laughed nervously

Donna, Rafh and Miky went to the first's lab and put the man 'gently' on one of the tables, knocking some things down, much to Donna's dismay, but that is where she started to try and understand what those squirrel were doing inside the homeless' stomach

Rafh and Miky watched as Donna does... whatever she is doing, however, Miky seemed to realized something, and she wanted to show it to her short tempered sister

"Want to know what was the first thing they did in my comic when they brought the infected guy to their base?" Miky asked and showed Rafh a page of her comic which the character was doing the same thing as Donna: examinee the infected

Of course, Rafh answered with a 'hunf' and pushed Miky away. Donna kept examinee the guy, and what she found out was something that creepy her out and that would hunt her and her sister down soon...

Ben's P.O.V

After the... awrkard moment between me and the turtles, and they leaving, I keep my research on these Mutagen, to which made me remember how this mission started

Flashback

After the flash died down, in front of me was an anthroporphic frog wearing green cloths with the Ultimatrix symbol

"Azmuth?" I asked surprised

"Hello, Ben, unfortunately, I'm not here to chat... or give you the Master Control"

I just looked at him with a deadpanned expression "When are you?" I sarcastically asked, to which he ignored

"Tell me, what have you been doing recently?"

I shrugged "I've been in a fight with these brain like aliens"

Azmuth seemed to be thinking of something "And was there... something stange in that fight?"

I'm pretty sure that now I know where he is hiding to "Yes, there was this strange green liquid... it was glowing and these aliens, the Kraang, were trying to protect it..." I tried to lie to him, so he couldn't know about the turtles, unfortunately, he had it covered

"But something happened that these strange green liquid spread all over the city"

I sighed "The Ultimatrix sent you the reading, right?" The creator of the Ultimatrix nodded

"Yes, and as far as I can tell, it isn't from this universe, maybe even this dimension..." Okay, that last part caught my attention

"You're saying that this can be another inter-dimensional invasion against Earth?" I asked, to which he unfortunately nodded

"And that's why I need you to tell me everything!" He said seriously

'What do I do? I can't just tell him about the turtles... but...' I sighed and looked at the eyes of the Galvan "Okay, Azmuth, I will tell you, but I ask you to keep some... 'details' in secret, so call my Grandpa in a private line, please..."

Azmuth looked in my eyes, probably trying to discover what is that important, however, he accept my request and seconds later, a hologram with my Grandpa was in front of me

"Azmuth, what is i-Ben?! What are you doing with Azmuth?" He asked

"It is more of a 'why Azmuth is with me' thing'" I joked, to which Azmuth rolled his eyes with a little smile while my Grandpa just smile "Anyway, I need you two to keep this a secret, so listen carefully..." I told them all about the battle in the ship, which is being analyzed by the Plumbers, and of course, I told them about the mutant female turtles

Needless to say, the two were a little surprised, but agreed to keep secret about the turtles

"But are you sure you don't want back up?" Grandpa Max asked me in worry

I shook my head "I want to be their friend, if I ask for back up, they may think I'm trying to arrest them" I explained

Grandpa Max nodded before leaving, probably to think about the Kraangs

Azmuth looked at me "I understand the need to keep this secret, so you can count on me, but I need you to collect this 'Mutagen' so I can analyze it and find out how it is made, what it does and a cure if needed... for now, the Ultimatrix can only say it is a 'Unknown Substance' but I reconfigured it so you can find it. For now, this is everything..." Azmuth's body started to disappear, a effect of his teleportation device "Good luck, Ben Ten" He said before leaving

Well, I can only say one thing

"Time for a Mutagen hunting!"

Flashback ends

And that is how I get to met up with the turtles, a total improbably and unpredictable incident

Well, it is normal in a crazy life like mine

However crazy my life is, it is not quiet, by a long shoot

"'Mutagen' infection detected! Alert! High levels of 'Mutagen' detected in single individuals!" The Ultimatrix shouted

I looked at the gauntlet and a hologram disc appeared, it showed nine red points with four of them brighter than the others and another point, however this last and tenth point is green, which showed where I was in comparison of the red points

I started to run until I stopped at an alley, right above the red points

'Please, tell me they are fine!' I thought as I entered the sewers

I'm worried about the four Mutant Ninja Female Turtles... I had no time to praise myself for that name, thought I fell like something was missing... Anyway

"It's Hero Time!" I thought as I selected an alien and the familiar green flash of my transformations appeared

Hold on tight, girls, I'm on my way!
