Pom Pom is the female counterpart of Boom Boom, and has first appeared in the 3DS game Super Mario 3D Land. She only attacks using boomerangs, and once stomped on, will try to crush Mario. There is a hidden technique at that moment to get lots of life: Stand on her shell while she is stomping. This will cause you to get 1-ups. She appears in Super Mario 3D World as a boss.
