Baku Baku Animal is a falling block puzzle arcade game released by Sega in 1995. Outside Japan, the game was released as simply Baku Baku. The game is dedicated as Sega's first ever Network Compatible PC Game. A Sega NetLink compatible version of the game was also announced, but never released.
The player must line up falling blocks of animals and foodstuffs. When an animal is aligned adjacent to a tile of its favored food, the animal eats the food. Larger groups of connected food of the same type scores higher when eaten.
When animals eat foodstuffs, they also make random blocks fall on the opponent's area, right after the currently falling blocks. The object of the game is to make one's opponent unable to place more blocks.
