So, this is my first time drawing something in YEARS. Tried to emulate the Adventure Time style, but my lines are a bit too clumsy.
Anyway, this is Marbles the Candy Sphinx and she is what happens when Princess Bubblegum, while high on Pixy Stix or something, decides to make another one using her and Marceline's DNA. Moments later she was chewing on Peppermint Butler because Princess Bubblegum + ancient irradiated half-demon vampire is not a good combination. And yes, I totally ship Princess Bubblegum/Marceline.
