The Minister approaches the King to tell him that his only daughter, the Princess, wants a new pet. But the King says she already has too many, and she can't take care of so many animals. Thus the Minister proposes a contest of skill and daring to select the Royal Zookeeper. Master Piggy then sends his pupil, Polly, to participate in the contest.
Baku Baku Animal is a puzzle game with elements similar to Tetris . It has three different play modes: practice, normal, and hard. The game can also be played by two players against each other (except for the Sega Game Gear version).
The objective is to pair animal heads with their respective food. If an animal head falls, you must make it fall on a pile of matching tiles. There are bonus items, such as the "BB coin", which will appear at times and remove piled tiles from the playfield. These removed tiles will be sent to the opponent's playfield all at once, increasing the difficulty of the task. Polly will face several contestants, and she'll win when her opponents' playfields are piled up.
