Jigglypuff (anime)/Anime/History/AG

Jigglypuff appeared only once in the Advanced Generation series, in A Poké-BLOCK Party!. In this episode, it was revealed to have traveled to Hoenn, and was overjoyed to see Alanna's not falling asleep while it was singing, unaware that this was due to Whismur's  Ability.

Jigglypuff was later referenced in Caterpie's Big Dilemma, which featured a karaoke microphone with a miniature Jigglypuff on it, holding its own tiny marker.
