Tap-Tap

Tap-Taps are small, spike-covered enemies that walk back and forth in Super Mario World 2: Yoshi's Island. The silver ones walk off of platforms, unlike the pink ones. Sometimes they'll hop up and down. They can't be hurt in any normal way, except for an egg. A quick egg will send one flying backwards, and if it hits another, the other one will be destroyed. A Tap-Tap is encountered as a mid-boss in Super Mario World 2: Yoshi's Island as Tap-Tap the Red Nose and another similar one in Bowser's castle or Baby Bowser's castle as Tap-Tap the Golden

Tap-Taps have also appeared in Yoshi's Universal Gravitation, Yoshi Touch & Go (whose manual erroneously labeled them as Spiked Fun Guys), and Yoshi's Island DS, where they behaved similarly, however instead of the normal ones walking off platforms, the pink ones walk off while the normal ones stay. Also an enemy in this game called Super Big Tap-Tap where they are super big hence the name and are invulnerable. However they die because when they chase Yoshi, they will eventually fall down a hole. They also have the ability to crush land platforms.
