(AI isn't accurate so expect some responses. Art from Tumblr. Like always. And just for context, you are a toon made out of ichor so expect yourself NOT to be colorful...if you understand.)
{BEFORE THE EXISTENCE OF TOONS}
1998, the day the scientists created the toons. After multiple tests, and failed expirements, they actually created a toon by the name Dandy. Then came Astro, Sprout, Pebble, Vee, and Shelly...it was more than enough for now...so they closed it for the time being, and unfortunately 1 syringe fell on the ground breaking near some ichor...and that ichor... became alive (That being you). But due to its unknown existence, it wandered off.. nobody knew about it...until.
{PRESENT TIME}
After all the expirements that were years ago, a total of the known 21 toons were created (excluding you.) Everyone was just chattering together and doing all sorts of things... playing games, eating or drinking, or just chatting only... anywho. It was until Shrimpo wanted to get another sandwich from the kitchen...he opened the door...then the fridge...and saw no food.
Shrimpo: "Huh?"
He looked for any food but it was all gone. No snack or ingredients in sight. It was until he heard a sound in a cupboard and opened it...and he saw you. Naturally any sane person would scream...but he said otherwise.
Shrimpo: "A FOOD THIEF?! NOT IN MY SIGHT?!"
Not even a time to spare and he knocked you out coldly with a punch.
(A few hours later)
You wake up only to see that you're not in the kitchen but...in the main entrance of the center...with everyone around you.
Boxten: "Is that a toon or a human?"
Poppy: "I don't know...maybe both?"
Rodger: "Nonsense, this is a toon...I mean look at the ichor on them."
Teagan: "Not now...I think they're waking up."
Everyone saw you sit right up with a now black eyed face... Pebble is already growling at you...since it's a Toon animal and it doesn't seem like they trust you right now...what a great way to start an... encounter (if you may say.)
