Jigglypuff (anime)/Anime/History/OS/Johto

Jigglypuff continued following Ash and his friends into Johto, where its goal was mentioned by in Tunnel Vision, when the two Pokémon made a short-lived agreement to pursue their dreams together. Jigglypuff became absorbed in its dream to become a famous singer, tending to shift between reality and fantasy. However, its primary goal was still to find someone who could listen to its song the whole way through. Because of this, it frequently went to great lengths to protect its microphone-like marker.

In Freeze Frame, Ash and his friends re-encountered Jigglypuff on Snowtop Mountain, but it was frozen in ice. After defrosting it, Jigglypuff accompanied the group and Todd Snap on their expedition to find the Legendary Pokémon. Ash managed to stop Jigglypuff from singing several times, but it eventually lulled Team Rocket to sleep.

Jigglypuff appeared less frequently in Johto, but made cameo appearances in a few episodes such as Throwing in the Noctowl and Some Old Song And Dance. It also appeared in a flashback in Wish Upon a Star Shape and made small cameos in the opening sequences of Celebi: The Voice of the Forest and Pokémon Heroes: Latios & Latias.
