Tamagotchi Hoshi is a sentient, personified planet with expressive facial features, including prominent lips. After Oyajitchi becomes frustrated and inserts a sake bottle into the planet’s lips, the entity consumes the alcohol and becomes intoxicated. This state causes the landscape to warp and shake, while the planet’s voice deepens and grows aggressive.

The disturbance from its loud singing and violent shaking proves unbearable for the resident Tamagotchi population, leading them to evacuate entirely using UFOs and Eggcopters. Tamagotchi Hoshi then demands more alcohol from Oyajitchi, who refuses, insisting it has had enough. As one of the few entities that communicates using proper language, the planet’s actions directly cause the Tamagotchi species to migrate to Earth.
