Sneaky Spirits (しろいおばけ, White Ghost) are enemies from the Rhythm Heaven series. They are one of the three Smash Run enemies to represent a universe that has not been represented by a character or stage, the other two being Bacura and Pooka.
Sneaky Spirits appear in the minigame Sneaky Spirits in Rhythm Tengoku, which reappears in Rhythm Heaven Fever as an Extra Game and Rhythm Heaven Megamix. The goal of the game is to knock the ghosts back into their house as they rhythmically pop in and out from behind a fence.
Sneaky Spirits appear as enemies in Smash Run. They are rare and hard to hit, as they constantly move forward while popping in and out the ground. However, they drop star boosts, which raise every stat, when defeated.
As a random event with a short duration, large groups of Sneaky Spirits can appear.
