From The Song of Jigglypuff through the end of the Johto series, a wild Jigglypuff followed Ash Ketchum's group, intent on performing its trademark song without causing its audience to fall asleep. It rarely if ever succeeded. Anything that fell asleep after hearing the song, that Jigglypuff would scribble all over the sleepers' faces. After Johto, Jigglypuff suddenly stopped appearing, but it did feature in one early Advanced Generation episode. This Jigglypuff was voiced by かないみか Mika Kanai in the Japanese version.
Marina also has a Jigglypuff. She used it to battle against Jimmy's Beedrill.
A green-eyed Jigglypuff was featured in Rough, Tough Jigglypuff, who was voiced by 池田千草 Chigusa Ikeda. Mitch wanted to capture this Balloon Pokémon for his daughter's birthday.
Smash Bros. Series
Jigglypuff is a playable character in all three Super Smash Bros. games, this Jigglypuff's alternate costumes, are usually associated with feminine headwear. As a result, most Smash fans refer to the Jigglypuff in the series as a "she". Strangely enough, Jigglypuff's Rest attack does damage in this game, even though in the Pokémon games Rest does no damage, but recovers damage.
Jigglypuff is a playable character. It is unlocked by completing 1-Player Mode once with any character and so is usually the first character to be unlocked. Jigglypuff's attacks in this game are Sing, Pound, and Rest. At times, Rest can KO an opponent from 0% damage.

It keeps all its attacks from the original game, althogh Sing keeps opponents asleep for less time, and Pound's button combo was changed. Jigglypuff also gained the attack Rollout, which varies in power (and ease of control) the longer it is used.
Trophy information
Classic Mode
This Balloon Pokémon invites its opponents in close with its big, round eyes and then puts them to sleep with a soothing lullaby. It puffs itself up when angry, and while it may look adorable, it's not to be trifled with; it knows several powerful techniques. Jigglypuff evolves into Wigglytuff after exposure to a Moon Stone.
Adventure Mode
Jigglypuff's normal attacks are weak, and because of its light weight it's easily sent flying. However, with its incredible midair agility, it seems to dance when airborne. Rollout is a powerful speed attack, but players must be careful not to fly off the edge. Pound does serious damage, and it can also help as a recovery move.
All-Star Mode
Jigglypuff can put its enemies to sleep if they are in range of its Sing attack, although the attack does not work on airborne foes. Rest puts Jigglypuff into a deep sleep, but at the instant it drops off, an intense energy force radiates out of the exact center of its body. If this force comes in contact with an enemy, look out! Rest is Jigglypuff's wild card.
Jigglypuff is a playable character that must be unlocked once again, yet plays no major role in the Adventure Mode: The Subspace Emissary. Jigglypuff's Final Smash hasn't been confirmed.
