Chiko was one of the plush toys Flora uses magic on to bring to life. After being brought to life, she makes occasional appearances in the Love & Pet store with Tecna. Chiko was also there with the other pets during Roxy's fight with Gantlos, helping Roxy gain her wings.
In "Winx Club Forever!," Chiko falls asleep beside Tecna while she works in her computer, and remains there beside her till the next morning.
In "Issue 60: Future Adventures," Chiko was the first Fairy Pet downloaded by the Winx when the group traveled to the future. Tecna was the one that picked it. Chiko almost flew away with the other pets because of the Trix magic, but they were saved in time by the Winx. In the end Chiko and the other pets went to the past, to the Winx timeline, and stayed with the girls.
In "Issue 67: Magix Virus," Chiko and the other pets appear inside the internet world and guide the Winx to a pile of data. Later on, the pets brought the emojis to eat the viruses and by such help the Winx to clean the internet from it. In the end the Fairy Pets exited the internet world with the Winx.
In Perle, among the others pets, Chiko is taken to Andros via Zoomix and participates in the summer party. Still in Andros, in Tecna's room, she was sleeping in a basket adapted as a pet bed when she got startled by Tecna screaming "BINGO!"
