Jigglypuff performing Sing on Pikachu, putting him to sleep.
Sleep is an effect in Super Smash Flash 2 in which characters enter when they have been hit or come in contact with a certain move that puts them to sleep. Characters are not able to move or do anything while under this effect, very similar to stun, which leaves them open.

Trivia
- Originally, when moves that are supposed to put characters to sleep came in contact, they would instead use their stun animation instead.
