Skully

Skully is a regular enemy in Kirby Mass Attack. They are Necrodeus's creations. Skullies are usually seen when Kirby obtains a Skull Key in any level, which teleports him to an intermediate room with numerous Skullies, one of which is carring a Skull Treasure Chest. If Kirby manages to nab the one with the chest, the rest disappear and the chest (usually containing a medal) is unlocked.

Skullies feature in the EOS Expedition minigame, where they either try to snatch Kirbys away or come floating with one in their jaws. Shooting such a Skully down adds one to the total Kirby count.

Appearance
Skully appears to be a white, floating humanoid skull permanently sheathed in a black cloud. When they attack, the whole of their bodies flash red.
