Whimp

Whimps are miniature Whomps that appear in Super Mario Galaxy 2. They only appear at Throwback Galaxy in the mission "Return of the Whomp King". In the second phase of the Whomp King battle, the king will stomp a foot to summon Whimps. After that, the Whimps will instantly start chasing after Mario or Luigi. Once they get close enough, they fall face-down attempting to crush Mario or Luigi. Luckily, unlike other Whomps, they only take a point of Mario's health and don't give him an instant death. Also, they are more fragile than regular Whomps and break as soon as they attack, meaning, to kill them all, one of the plumbers have to simply get the Whimps to attack.

Appearance
Whimps are about the size of Mario and Luigi. Their eyes are black half circles with red dots inside and no eyebrows. Their mouths are peanut shaped with one tooth on the top-right and a red tounge. Other than that and size, Whimps look exactly like regular Whomps.
