Mushroom is one of the 20 contestants in Object Odyssey. She's a trans character (male to female) she's very chill, and often doesn't help out in challenges, but later on she does learn to help out. She likes to draw, more specifically digital art! She's secretly quite nervous about this whole game thing. The only person she told about that is Quill, her best friend. If she could leave the game, she would. 

I'm fine with her being voiced by a male teen or male adult. I have a general idea of what she sounds like, maybe something similar to lightbulb from inanimate insanity, fan from inanimate insanity, or profily from bfdi. Idk that's just some ideas I have multiple voice headcannons for her, so I guess that gives you (if you're auditioning for her) an idea of what she should maybe sound like.
