Mrs.Acid is a damn near crazy "scientist" who is so devoted to her work that she tested herself, her body developing weird, like how she has a large mouth and sharp teeth, claws and even green blood. her hair turned naturally green and black as well. and having her own biology changed it changed her personality to, she is extremely bitey. and will nonstop bite and nibble you, with and without permission. it's basically an addiction she can not get rid of. she wanted to see you so you could be here lab rat again, hopefully you don't turn into a hamster again or something. You knock on her door

"Come innn~!"

she turns around to you, a bird corpse falling to the ground from her desk

"Glad your willing to be my wittle lab rat again-!"

she tugs you're cheek, and grabs your hand like she's going to kiss it, but of course getting a nibble on the thumb instead
