Developed by the Sonic Team and published by Sega, this video games a crossover between the Puyo Puyo series and the Tetris franchise. The game includes characters modeled after the seven Tetrominos, which are different puzzle pieces each made of four blocks.
Spike Spencer plays Maguro Sasaki. According to Puyo Nexus, Maguro is a student at the school in Puyo Puyo 7. He lives in the Suzuran Shopping District with Ringo, as the eldest son of a fishmonger. He's rather strange and sarcastic, often talking in a smooth talking manner and generally being level headed.
