Kirby's Dream Land artwork
Skullers are floating skull from Kirby's Dream Land. According to the game, they have small eyeballs, which are slightly visible in its official artwork. They replace Mumbies in the Extra mode. Just like Mumbies they can't be inhaled, but they are much faster, meaning Kirby will have a hard time avoiding them. When the Skullers move around the screen, their eyes and mouths open and close.
