Not without reason. Chucky - looks like a mouse, which for some reason made me think about "chuck e cheese" from Sam & Max, which in turn made my thing about Chucky from Child's Play fame. Makes perfect sense right!?
Bobcat - his head bobs up and down which initially make me go for 'bob', but that is just waaay to easy. I thought of Boppin but that reference is too obscure. Eventually I settled on Bobcat because it looks nothing like a bobcat, but I've always enjoyed Bobcat Goldthwait's work (egad what a name!)
