I just decided to make up some random things I thought Levi and Kevin would do! Some of it cute, some of it comedy, some of it just 'I don't know what I'm doing with myself', so let's get to it!

🍕Sometimes, when Levi just doesn't feel like doing anything during Donnie's lessons, she'll start drawing on the desk, and every time Donnie turns to her, she'll hide the drawings with her arm. She'll continue the process and see how long she can keep it hidden. Her longest record is half an hour.

🍕Kevin and Mikey like to throw paint around the lair just for fun.

🍕Levi sometimes steals Leo's sword and goes through multiple portals just because she thinks it's fun. She's nearly died several times because of this, and has accidentally destroyed more things than she can count.

🍕When it gets really cold, Levi hugs Kevin and doesn't let go since his floof provides warmth.

🍕When it gets really hot, Levi fans herself with her tessen. She often accidentally cuts herself because of this.

🍕The last time the rat flu happened, Levi and Kevin yeeted themselves out of the lair as soon as possible; They didn't know what this rat flu was, and they didn't want to face it first hand.

🍕Sometimes when Levi's out on the surface, she'll see her parents and she often tries to yell at/attack them out of pure anger. Ever since the last incident where she left a large scratch in her father's cheek, either April has to come with her, or one of the turtles or Kevin have to stay in the shadows and keep an eye on her so that doesn't happen again.

🍕Raph and Levi sometimes talk and give each other tips about being the oldest sibling; Levi showing Raph he doesn't always have to be so overprotective and strict about being the oldest, and Raph showing Levi how to deal with her kinds of problems more seriously.

🍕One day, April took Levi to school with her. By the end of the day, she somehow managed to blow up several things in the lab, pop several dodge balls and two basket balls during Physical Education, and get paint all over the room during Art. She was never aloud in that school ever again.

🍕Sometimes when he's bored and Mikey can't/doesn't want to throw paint around the lair, Kevin traps himself in a bubble shield with his naginata and goes around the lair like a hamster in a hamster ball. It's actually pretty easy to control now that he's gotten used to being trapped in his shields so much anyways; The hard part is getting out.

🍕Kevin actually really likes to be pet, especially under his ears.

🍕Kevin almost always gets things like paint, food, drinks, etc. stuck in his fur.

🍕Sometimes, because of how long Levi's hair is, it would cause her a lot of trouble; tripping on it, gettin it in her food while she eats, accidentally getting it trapped in doors and such, etc. That's one of the reasons she ties it up.

🍕Sometimes, when Levi and Leo are alone and bored, they go out and have the most random contests, like 'Who can use the other person's weapon better?' (usually Levi) 'Who can do the most tricks on a skateboard without falling off?' (usually Leo) or a personal favorite, 'Who can go through the most portals to the craziest worlds and last the longest?' (Most of the time, none of them win- They both turn into huge babies and run back to the lair screaming)

🍕Kevin has a hoodie of pretty much every pattern and every color. It's amazing just how much stuff humans throw away like it's nothing. The reason he usually wears his dark blue hoodie is simply because it's one that Levi game him herself and he's grown pretty emotionally attached to it.

🍕Being artistic, people- and by that I mean the turtles and April- always think that Kevin would be the kind of person to carry a sketchbook everywhere he went. But really, he's not a big fan of that kind of art stuff. He doesn't like sketching realistic things, and would rather just paint/draw whatever he wanted.

🍕Kevin is actually a pretty big fan of tinkering. He likes to go through the dumpsters on the surface and see what he could find, and see what he could make. More than often, if Donnie tries to get him to make an invention with some of his things in the lab, it ends up exploding in their faces, or ends up trying to kill everyone.

Welp. Hope you found that fun or something-
Thanks for reading! Peace!
