His first appearance was in An Unexpected Event, with Bloom when he suddenly felt that something was wrong and warned Bloom about Stella's fight against Knut the Ogre.

Abilities and Skills
Kiko is just an ordinary pet bunny to Bloom. He does not have powers, but was brought to power by Bloom, who gave him wings in the finale of Season 2 and Roxy, who gave him the power to speak in Season 4. Kiko is, however,suspected to have some sort of magical qualities, which are shown early in Season 1; he passes through Alfea's barrier that only allows magical creatures. This is confirmed in the Season 1 finale when he is shown flying to get himself and Icy's pet duck to safety then hides in a hole. He is also seen in the Secret of the Lost Kingdom, where a little girl in the flower shop saw him floating. He is shown flying again in the The Shadow Phoenix, while carrying Bloom's headband. In the last episode of the Season 2, Kiko gains wings and becomes a pixie-animal. However, since then his flying ability not shown.
