I saw someone with a 'sona that had a rainbow tongue, made a small comment about how maybe they should take away the black lines cuz it looked like a worm or a rainbow grub.

They said there's no such thing as a rainbow grub.
Pshaw, no such thing as a rainbow wolf either.
She also said grubs are disgusting.
Challenge accepted, here's an adorable chubby rainbow grub.

He's cute as hell but I don't have anything to use him for, so the next person to note me can have him for $10. Make him a pet, use him for micro vore or something, maybe have him grow into a rainbow hercules beetle. Ten bucks.

Sold. Grub now belongs to Sheba_Metaluna
