If you don't know Catbug, basically: [link]
He's from Bravest Warriors, another show by Pen Ward (who made Adventure Time).
Though a lot of people imagined Catbug as a girl, I think he's a boy since he's voice by a boy hehe *u*>;;
May sell as a print if it's popular enough, Idk how popular BW is these days compartively speaking to AT?
