What was the one Nintendo game where you played a monkey that bounced balls on its head to kill enemies?

At least I think it was a monkey. It might possibly have been an NES game; all I know is that it's old. Anyway, so this tiny ball would come down from above and you would have to bump it with your head and make it bigger, and kind of go up the level and when it hits an enemy it kills it. Does anyone know the name of it?What was the one Nintendo game where you played a monkey that bounced balls on its head to kill enemies?I think it's Super Monkey Ball you are talking about. I have that for the ps2, and you play as a monkey in a ball.
