A Protobatter is a round creature that holds a club and resembles a Flurry. It is found inside the Pump Works of Bowser's body in Mario & Luigi: Bowser's Inside Story.

The three size variations of Protobatter

It grows up to two to three times larger whenever Mario and Luigi attack it. It also makes shockwaves with its club like Clumphs from Mario & Luigi: Superstar Saga and attacks by spitting a piece of batter and slamming it with its club at the bros. The direction it holds its club is to indicate which one of the Bros. is being attacked. This attack can be countered with the hammer. It may miss the swing up to two times in an attempt to lower the player's guard. Protobatters also have stronger faster cousins called Pwallops that appear in the Energy Hold.
