A piece I commissioned TFSubmissions for! (They drew it, colored it... Everything! All the art is by them! Not me! Need to make that as clear as possible! All I did was design the characters)

Meg finds herself in a peculiar situation while visiting her friend, Sally. Spying a bottle of orange juice on the counter, Meg's sweet-tooth gets the better of her as she drinks it up! Unfortunately, the juice inside was actually one of Sally's potions she was practicing for classes this semester. She figured it wouldn't hurt to just reuse one of the old glass bottles she had, much cheaper too! But she didn't count on her friends spontaneous behavior.

Soon Meg found herself dwindling down as she shrank further and further into her seat. Her ears growing out, fur spreading across her body, her mouth stretching out into an adorable muzzle and a long, thin tail sprouting from her backside! Doing her best to stay calm now that she'd shrunk to 1/5th of her size, she waited for her friend to return and hopefully not be too mad that she drank her school project... And maybe change her back soon!

While a little upset she has to redo her homework, Sally was pleasantly surprised to find that her friend, who normally towered almost a foot taller than her, had been shrunk so small she barely reached up to her knees! That, and with Meg's adorable possum face and now rather squeaky voice, it was hard to stay mad at her.
