Chikunto

Spiked Ant are simple Ant enemies, but are able to protrude spikes from their bodies. If Mario jumps on them, he will gain damage. They should not be jumped on while the spikes are out. They only appear in the Macro Zone of Super Mario Land 2.

Usually they will walk with their spikes retracted, and then stop to stick out their spikes as Mario gets near. Mario must wait before he can jump on them. They are defenseless to a fireball, regardless of whether or not their spikes are erected.
