There is a bee hive- and Tubbo absolutly loves to hang around the bees there, and on several occasions has made Tommy go inside to get bees.... Which doesn't always end well
At some point the zoo got a baby panther and Ranboo was able to name them Enderchest :3
There was only ever one time that Tommy was left completely alone at the zoo- and after that everyone regretted it as he lead an army of animals to "attack" the humans as a prank-
The biggest bonding experience Tommy and Techno have is sneaking into the polar bear exibit to cuddle with Steve and take naps (no Wilbur and Philza totally don't have pictures, what are you talking about- 👀)
None of the humans actually know about Tommy's Borrower tunnels, they just think that he's really good at hiding and getting around- until he tells Wilbur, to which the vet was very surprised that he was the first human Tommy trusted enough with this knowledge and not Philza
Although Wilbur loves Friend, and lines to hang out with Tommy- he does not want to be around both at once, not since that one time when Tommy fell down into her wool and got lost for an entire day-
When the holidays finally arrive, all the humans offer to let Tommy come home with them until they open the zoo back up- but he promptly declines, both not fully trusting them (the first time holidays time arrived) and not wanting to leave his home- so instead the humans show up at the closed zoo to celebrate with Tommy
Although Schlatt and Quackity lost one Borrower for their zoo- they soon gain another... two actually!!! Charlie and Sneeg- two crime Bois that are ready and reporting for duty to be the bestest spies!!!! >:3
In this world superheroes esxsist. Some people are born with powers such as Charlie: he can size shift (although he doesn't have complete control over it, aka, it takes him a while to grow back to normal) and can turn his body/parts of his body into slime (but he himself isn't made of slime)
Charlie actually grew up with his closet freind being a Borrower named Sneeg- and even after he became an adult Sneeg still stayed with Charlie wherever they went
Recently Charlie and Sneeg move into this apartment complex, both knowing that even if Charlie has an apartment and gets a job for rent- he's still going to be a Borrower like Sneeg since that's how they spent most of their childhood
There's one problem though.... This apartment complex belongs to the hero team Innit Incorporated, a buissnuss that used to be run by the top hero before he died and his teenage kid, Tommy inherited it
The complex was supposed to be a way to have all the heros of the incorporation live close enough together in case of emergencies, but of course, a teenager can't exactly make money the way his dad did, so Tommy rents out a few apartments to keep it open
You see the main problem with Innit Incorporated is that they don't see Borrowers as people (even though they don't even know Borrowers esxsist yet) which means that Sneeg and Charlie will have to be careful when moving throughout the complex.....
Or not
Both boys are very chaotic and neither really care about being caught or seen, seeing as Charlie can just grow back to normal size and everything will be okay
And so- slowly- all the tendants of the complex each spot a Borrower
Wilbur (a hero that has the ability to turn invisible and go through walls) was the first to find and catch Sneeg. He was surprised however by how carefree and unworried the tiny person was at being trapped in a jar... So he decided to have a little fun. Wilbur let Sneeg go and told them they could continue living off supplies from his apartment (Sneeg doesn't exactly care about the rules and did tell Wil what a Borrower is) but if Wilbur ever catches him he "I- I- uuuuhhhh.... I get to uh- I get to beat you with this bucket!!". It seems like a fair enough deal to Sneeg and he's quick to agree- but after that he starts going to Wil's apartment more just to tease the hero and laugh as he fails to catch him (Sneeg and Charlie grew up playing games of cat and mouse- he knows how to not get caught)
Next to see the tinies was Tubbo. Tubbo being a hero with bee-like powers but unusually is not the size of a bee. Basically, Sneeg and Charlie were borrowing together this time (they obviously don't need to, but they wanted to, because it's fun) and didn't know that Tubbo was still home while Ranboo was out- so instead of avoiding the human, they decided to fuck with him. At first they just moved things so Tubbo wouldn't find them while he was trying to work on something (building a little contraption) but as soon as Tubbo finally spotted them, the game of cat and mouse was on. Tubbo ran around the apartment all day trying to grab, stomp on, and catch the tinies but failed everytime and only got more mad/annoyed as the tiny people laughed at his failed attempts. Obviously Charlie and Sneeg had to leave after a while, but they made it plan to visit Tubbo and continue the game (well, game to them) and see how close he could get, and once Ranboo joined in it just got even more fun.
Tommy was the first to know about Charlie, seeing as he got his dad's database of people in the city who had powers, and once he heard rumors of a tiny causing havoc he went to check out Charlie's apartment. What Tommy did not know about was Sneeg. So as Charlie acted like there was nothing out of the ordinary Sneeg did a bunch of stuff to annoy Tommy as Charlie acted like Sneeg wasn't there at all (he knew they were there, it was just fun to annoy people)- after that, everytime Tommy came to visit Charlie acted like he had no powers and was just a normal human without a Borrower brother as Tommy got more and more annoyed as Sneeg did more and more obvious things, and Charlie just pretended like nothing was happening
One of the few tendants they visit that they know won't try to catch them is Niki (she has mer powers). They try to visit her at least once a week after she first saw them and immediately awed, cooing and giving them free sweets. So the tinies obviously love to got visit her as she'll give them loads of sweet stuff, hold them gently, and just be an amazing human. (They especially love being there when any of the other tendants are there though, as the other heroes will be silently seething with anger as Niki cuddles with the tinies that "would never do anything wrong! 💖" And Charlie and Sneeg will just- smirk at the other person because they can't do anything while Niki is there)
Finally, there is The Crow Father. The hero who became #1 after Tommy's dad died. Philza (the hero's real name) did eventually get a visit from the chaotic tinies but didn't really mind as they seemed to just be chilling and weren't really causing many problems in his apartment. Of course, he couldn't interact with them as he "wasn't supposed to treat them as people", but he could just sit there and let them vibe. He also sometimes took the Charlie approach whenever Tommy would come over while the tinies were there and would just pretend they weren't, even if Tommy saw them.
Techno is just some guy in the complex (it is suspected he has powers, but nobody knows for sure, not even Tommy) and kinda just watches the chaos unfold
Basically the au is: Charlie and Sneeg are tinies with a complete disregard for the Borrower rules and a complete thirst for chaos-
