Peppillon is a different colored variation of Betterfly. It has pink and white on the top pairs of its wings, with white shapes making eye shapes with curved eye-like shapes underneath the eyes and complete with eyebrows. Then the bottom pair has green wings with white swirls that represents wind. The face is purple with a white curve on the top, his eyes are red with a darker yellow circle in the middle. There appears to be a white tuft like shape on the head. His body is black with a small area being purple and pink colored shapes, then the rest is black and white stripes. What appears to be red fluff is worn around his neck like a scarf.
It is a very cheerful yo-kai as within the episode was only seen once not smiling.
Peppillon's power was that whenever its wings flap, scales come off.
When someone breathes in the scales, they feel amazed and excited about everything.
Peppillon debuted in EP016, when Nate and his family were celebrating spring break. Before even getting out of the house, the butterfly Yo-kai had already possessed Nate's parents Aaron Adams and Lily Adams, making them extremely excited about the trip. During the car trip, Nate, Whisper, and Jibanyan fell under the possession effects as well. However, not too long after arriving and during sightseeing the waterfall, a sudden downpour caused by Drizzle dispelled the effects and Peppillon flew away.
In EP027, Peppillon was seen in Yo-kai-lifornia where he was among the Yo-kai awaiting the release of the Yo-kai Watch Model Zero.
He is first summoned in EP125 and possesses Whisper and Fuankan.
