Spiked Fun Guy (Super Mario World 2: Yoshi's Island)

A Spiked Fun Guy is a small green type of Pokey in Super Mario World 2: Yoshi's Island and its reissue, Yoshi's Island: Super Mario Advance 3. Spiked Fun Guys inhabit a handful of stages. Ordinarily, they merely move back and forth along the ground, bouncing back when they collide with a wall. As they move, they rapidly contract their heads up and down. A bouncing version in a pot also exists.

 * Shogakukan guide: 小さくてもサボテン. 踏むとイタい目に会う. (A rather small cactus. If you step on it, you will get hurt.)
 * Player's Guide: A fun guy? Oh, really. A couple of jokes from this party animal and everyone will be snoozing.

 * Shogakukan guide: さくてもサボテン. ふむとイタいにあうぞ！にぶらがっててきたり、にっててくることもある. (A rather small cactus. You'll be sorry if you step on it! It sometimes hangs from a balloon or rides in a pot.)
