Piko (Japanese: 少年ピコ Young Piko) is a minor recurring character who first appeared in Why Not Give Me a Z-Ring Sometime?. In Japanese, he and Nene refer to Acerola as "Big Sis".
Piko is close friends with Nene. They asked Acerola to read them a story, which she did. They later watched as Acerola was captured by a Gengar.
Piko reappeared in Tough Guy Trials! at Acerola's house alongside Nene.
