A Yoshi's Story Spiked Fun Guy
Spiked Fun Guy is a type of Pokey which is a Tap-Tap lookalike. They inhabit the jungle levels of World 3 and castles in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3 and infest the Torrential Maze and Jelly Pipe in Yoshi's Story. Unlike Tap-Taps, Spiked Fun Guys can be eaten and made into eggs. In Yoshi's Story, Spiked Fun Guys are purple; in Yoshi's Island, they're green (resembling cacti), and sometimes appear in pots, as Potted Spiked Fun Guys. They also can be taken out by eggs.
