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 a small song (Just says Jigglypuff in a musical tone) to put players to sleep. The player will be immobilized while sleeping, and will be completely open to attacks. 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
