Jigglypuff are usually famous for their sweet voice, but this particular Jigglypuff has a problem with its voice, so Ash and Co. helped it to regain its voice, but Misty didn't catch it so whenever it arrives or whenever it comes on before a stage, it tends to sing, causing everyone who hears it to fall asleep. It seems to be unaware of its singing capability, and becomes annoyed when its audience falls asleep. When this happens, it uses its marker to draw markings on the faces both people and Pokémon alike as punishment.
First appearing in the The Song of Jigglypuff, Misty attempts to capture it, but Brock notices that this Jigglypuff has a throat issue. The group later helps Jigglypuff regain its singing capabilities, and upon singing to the group, becomes annoyed when they fall asleep. It rummaged through Ash's bag and found a marker, which it used to draw markings on their faces. Jigglypuff would later keep this marker to use as a "microphone" of sorts when it sings.
Jigglypuff later sang for the whole town of Neon Town, but because everyone feel asleep upon hearing it sing, it became annoyed and drew markings on everyone who attended. After that, it disappeared, but was shown to be trailing Ash and his group, all the way to Hoenn.
It is believed that it started on a journey to find the one whom listens to it. This journey is believed to have ended when the Gang encountered it one last time in Hoenn, where it found a Whismur that listened to the song all the way through, though its friendship with Whismur had ended rather abruptly.
This Jigglypuff later makes a reappearance in SM042, where it returned to Kanto. It emerges from the destroyed Meowth robot, where it proceeds to sing to group, causing everyone to fall asleep. As punishment, it drew markings on their faces. In SM043, Jigglypuff is shown to be on the plane carrying the group back to Alola.
It reappeared in the Pikachu short airing along with the 15th Pokémon movie.
