Overview
Different types of Baku Baku creatures are only encountered in Hidden World Zone 4. These creatures are found inside bubbles, either stationary or move around in linear patterns. At the same time, they are seen moving their mouths continuous pace. When the player lands on the bubble with Baku Baku in it and leaps to another bubble, the creature gets released out the bubble and starts slowly to follow Sonic. Larger bubbles contain five Baku Baku creatures at once and popping up the bubble releases them in similar way. Some of these larger bubbles are surrounded by green slime bumpers that can deflect Sonic or Iron Balls.

The player has to find a good leap point on the bubble with Iron Ball inside it and jump off it, while the Iron Ball will travel in a straight line in the opposite direction, where Baku Baku creatures are. These creatures are defeated once when they've got knockout blow from the Iron Ball. Also, if the player has reached far enough of following Baku Bakus, hairy creatures will turn around and move to the opposite direction.

Giant Baku Baku
A giant variation of the Baku Baku with white teeth appears at the mid-point of the auto-scrolling Hidden World Zone 4.

The creature arrives slowly from the left side of the screen and starts move forward while slowly moving its mouth. The large body of the Baku Baku pops all bubble around it broken and reflects all Iron Balls.

The player has to escape the giant Baku Baku creature, but also look up good time to aim the bubble with Iron Ball to its mouth when the giant hairy creature opens its mouth. When the player leaps forward while the Iron Ball manages to get inside the creature's mouth, the giant Baku Baku gets hit every time and splits huge amount of Animals out of its mouth. It then starts charge rapidly forward. After getting hit twice, the hairy creature summons large, green slime shield around it with regular size holes on it. Like previously mentioned, slime bumpers bounce Iron Balls back. However, if the player manages to aim another Iron Ball over slime shield inside the Baku Baku's mouth, the hairy creature is defeated and the player has cleared the Hidden World.
