It is extremely skittish and will burrow into the ground as soon as Kirby approaches, taking with it the Mirror Door. If this happens, Kirby must exit and re-enter the area to encounter Mirra and its door again. It can be defeated through many methods: the Star Spit, a long-range attack or various abilities (Wheel, Burning, Cutter, UFO, etc.). It gets KO'd if Kirby lands just one hit, leaving behind the Mirror Door it was stretched over.
The easiest way to approach Mirra is to have Kirby store up a puff of air and float along the ground, and KO it by expelling an air puff; he can usually walk/float on the ground up to, and stay right next to Mirra without scaring it away beforehand.
The name "Mirra" is a corruption of the word mirror.
- Mirra is the only regular enemy to guard doors. Others, such as Nidoo, merely impersonate them.
