Sing

Sing is a move done by Jigglypuff in the Super Smash Bros. series. It is executed by pressing Up on the Control Stick, and pressing B soon after. She will then sing her name in a musical tone to put players to sleep. The player will be immobile while sleeping, and will be completely open to attacks for a few seconds until the effect wears off. It can also be used to run away. However, it does not work for airborne enemies, leaving Jigglypuff open for attack. Additionally, sometimes the opponents will wake up the instant Jigglypuff finishes the attack. Sing does no damage, but is a good escape move.

Sing is actually Jigglypuff's signature move in the Pokémon series.
