Bob (Puzzle Bobble/Bust-a-Move) in Minecraft

Bob (Bobblun) as featured in Puzzle Bobble/Bust-A-Move (arcade).

Besides the limited tile palette, as stated previously, there are twin Bubs/Bobs in that game. This sprite of Bob is when he's the one who spins the wheel on the pointer mechanism (and yawns when idle). However, it is also used when the other twin Bub/Bob turns around to load another bubble.
This sprite has been chosen for Bob because he is put in this role in the SNES version's controls menu (and its true hard-to-get ending).
