Manzai

Manzai Birds is an Endless Game in Rhythm Heaven Fever. It was removed from copies released outside of Japan due to the nature of the focused dialogue around the game and replaced with Mr. Upbeat. It is unlocked after you obtain 32 medals.

Gameplay
The player controls a crow, and has to press A twice when the vulture stops talking. Sometimes the vulture winds up thrashing its head back, and then you have to press A+B to slap it. You get one point for every successful action, but one mistake and it's game over!
