Booler

Boolers are ghost enemies who appear in a few Kirby games, and they make their first appearance in Kirby's Dream Land. Following their debut, Boolers have only appeared in spinoff titles. Boolers have a round body, a wispy tail, and a long red tongue that they usually stick out.

Kirby's Dream Land
In Kirby's Dream Land, Boolers are only encountered in Castle Lololo. They either quickly chase after Kirby or move around in a set pattern. In the Extra Game, Boolers are replaced by Gaspars.

Kirby's Pinball Land
In Kirby's Pinball Land, there are two Bumpin' Boos on the lowest screen of Kracko Land. They are found at the top-left and top-right corners respectively, and each of them is circling around a Gordo. If Kirby hits the Booler on the left, a letter of "WARP" lights up, and if he hits the Booler on the right, a letter of "STAR" lights up.

Kirby's Block Ball
In Kirby's Block Ball, Boolers are encountered in four rounds: Stage 2-3, Stage 10-1, Stage 11-2, and lastly Stage 11-5. Unlike their earlier appearances, Boolers always float in place. Kirby can defeat a Booler by hitting into it, and in doing so, the Booler usually drops a Flip item.

Kirby Tilt 'n' Tumble
In Kirby Tilt 'n' Tumble, Boolers were given a friendlier look on their face, although Kirby still takes damage if he touches one. Boolers become angry if Kirby enters a Jump Hole, and some become angry if he goes near them.
