Puyo Puyo (ぷよぷよ) refers to a series of puzzle video games created by Compile and later Sonic Team. Puyo Puyo, originally released by Compile in 1991, featured characters from the 1989 RPG Madou Monogatari, also made by Compile. Puyos were enemy monsters in said game, as the rough equivalent of the slime monsters from the Dragon Quest game series.
