Sing

Sing is a Normal-type move recurring throughout the Pokémon series, and Jigglypuff's up special move in the Super Smash Bros. series. Unlike other up special moves, Jigglypuff does not get sent into the air but instead sings, sending out soundwaves that cause any opponents caught in them to fall asleep like in the games of origin. In Super Smash Bros. opponents with less damage remain asleep for longer, but in Super Smash Bros. Melee onward opponents with more damage remain asleep longer but can wake up faster by tapping the control stick or D-pad rapidly.

In Super Smash Bros. for Nintendo 3DS / Wii U this move is given two custom variants. The first one is Hyper Voice, another move from the Pokémon series, which is an attacking variant that has greater range and deals greater damage as it goes on. The second is Spinphony, which is slower and has a wind effect that spins opponents around in addition to dealing damage.
