Tamagotchi: The Movie
At the end of the film, when trying to find a way for Tanpopo to return home while the rocket ship is being repaired, Mamehakasetchi is able to track down Cometchi and arrange for it to pick her up. They meet it in a specially designated field, where there are glowing yellow flowers and tall stalks that bend down and become a staircase for Tanpopo to walk on. When Cometchi departs, it leaves a glowing trail of stardust in its wake that can be seen from all across Tamagotchi Town.
Cometchi's English name comes from the English word "Comet". Its Japanese name comes from the word "Suisei" (彗星), the Japanese word for comet.
