Finn and Jake are about to go on their craziest adventure yet... and they don't even have to leave the treehouse?! After helping Party God with his technical issues, these two best pals discover a tiny cube all by its lonesome in the middle of the woods. Not ones to leave the helpless so... helpless, Finn and Jake take their new friend back home and discover that sometimes the most harmless looking things can be the most dangerous.

Written by Danielle Corsetto (GIRLS WITH SLINGSHOTS) and illustrated by indie newcomer Bridget Underwood, Graybles Schmaybles is a refreshing adventure that only best friends can take.
