Tap-Tap

Tap-Tap is an enemy in the Yoshi series. It is a spiky creature that tends to make clicking sounds while walking. Tap-Taps are immune to standard attacks except an egg (even using an egg won't defeat it immediately it will just knock it backwards). The only way to destroy a Tap-Tap is to knock another Tap-Tap into one or to use a Chomp Rock or a special item.
