A Souflee (ケーク, Cake) is a rare enemy in Kid Icarus: Uprising.
Souflees are enemies introduced in Kid Icarus: Uprising. Though harmless, they are extremely fast and travel a set path. Their affiliation is unknown. Some even appear temporarily. Defeating one gives a large amount of hearts, the currency of the series.
Souflees appear as rare enemies. They move very often, making them difficult to hit, and intentionally avoid trying to get close to the player, but when defeated they drop large amounts of powerups.
An event in the Smash Run, called "Souflee Fest", causes Souflee to become considerably more common. The random challenge door Survive: Normal difficulty hosts one Souflee and one Orne: in said challenge the player is in a small room and must avoid the instantly deadly Orne, so chasing and defeating the Souflee before the timer runs out is very risky, albeit very rewarding.
In Smash Tour
A Souflee can appear as a random event. Bumping into it awards a player a checkpoint bonus, but resets their current checkpoints.
