Tap-Tap

Tap-Taps are small, spike-covered enemies that walk back and forth in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. The silver ones walk off of platforms, unlike the pink ones, but this arrangement was reversed in Yoshi's Island DS. Sometimes they'll hop up and down. They can't be hurt in any normal way, except for an egg. A Huffin' Puffin chick will send one flying backwards, and if it hits another, the other one will be destroyed. They're immune to most attacks, except ice breath and fire breath. A Tap-Tap is encountered as a mid-boss in Super Mario World 2: Yoshi's Island as Tap-Tap the Red Nose, as well as a similar obstacle in Baby Bowser's castle known as Tap-Tap the Golden.

Tap-Taps have also appeared in Yoshi Topsy-Turvy, Yoshi Touch & Go (whose manual erroneously labeled them as Spiked Fun Guys, which are actually a different species), 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. A large, invulnerable variation (with the ability to crush land platforms) known as the Super Big Tap-Tap also appears in Yoshi's Island DS.

 * Sorbetti, from Super Mario Galaxy 2, looks like it may be a Super Big Tap-Tap made out of snow.
 * The name of Tap-Taps may come from the distinctive clicking noise they make as they walk.
