Mattel already made the Nibbler a vehicle.
Thanks to someone on the Glyos forum for pointing out how Nibbler-esque the face on this Imaginext toy is. The local Targets were blowing them out for ten bucks, so I said "what the hell." It's even motorized!
Mark this down as project number 1,483 that I will never complete: painting this thing in original Nibbler colors.
