Spriteling

"Wario! Hi! I've been waiting for you!  I'm one of the Spritelings of the forest!  I have really bad news.  That evil black jewel you stole is sucking up all of the negative greed energy swirling around in your castle, and terrible things are starting to happen!  Honest!"

The Spritelings are forest sprites who assist Wario in Wario World. They come in five colors and will give him hints and tips to defeat the Black Jewel if he rescues them from their cage prisons. Despite their friendly demeanor, they are listed in the enemies section of the Wario World instruction manual, although Wario claims that this is because they are his "enemies' enemies".

Each of the eight levels in Wario World contains five Spritelings to rescue, for a total of forty in the game.

Wario seems to show dislike for the sprites, instead preoccupying himself with regaining his treasure. However, it is the Spritelings that rebuild Wario's ruined castle at the end of the game, and the more Spritelings Wario rescued throughout the course of the game, the better his new castle will be, though the unrescued ones will also be in the ending still in their cages. In the ending, a red Spriteling will talk to Wario and after the first line, extend his arm out.

Spritelings live in the depths of the Sacred Forest. They are a tribe rather than a group, and they prefer secluded areas.
