Tsukitchi (つきっち) is the moon of Tamagotchi Planet. He can be seen in the night sky.
Tsukitchi resembles a yellow crescent moon with a face. He has beady eyes and a pink beak. Sometimes he makes different face expressions, such as sadness, depending on what's going on back on Tamagotchi Planet. He is different from a real moon because he never goes through different phases, instead, he always resembles a crescrent.
In the Anime
Tsukitchi has appeared in Tamagotchi: The Movie, Let's Go! Tamagotchi, and every entry in the Tamagotchi! series. He is usually a silet background character. Sometimes he talks (although rarely), and acts as a narrator for the show.
Tsuki is Japanese for "moon".
