Sing

Sing is a move done by Jigglypuff in Super Smash Bros. Melee. It is executed by pressing Up+B. 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. However, it does not work for airborne enemies.

Sing is an acual attack in Pokémon, and is also Jigglypuff's first attack.
