Spriteling

The Spritelings are forest sprites who assist Wario in Wario World. They will give him hints and tips to defeat the Black Jewel if he rescues them. Despite their friendly demeanor, they are for some reason listed in the enemies section of the Wario World instruction manual.

Wario seems to show dislike for the sprites, preoccupying himself with things of greater importance (i.e. regaining his treasure).
