Tamagotchi 'Round The World (くるくるかいたくプラネット) is a Tamagotchi-based game developed for the iPod and was released November 4, 2008.
The objective of the game is to raise three planets by interacting with the environment on them. Users can choose to play as Mametchi, Memetchi, Kuchipatchi, or Violetchi. While the player spends much time caring for the planet, the user must also care for the Tamagotchi character itself, or they will refuse to cooperate with the user.
