Planet Popstar
Planet Popstar is a distant planet shaped like a yellow five-pointed star, typically crossed by two white planetary rings, that is home to a majority of the main characters in the Kirby series. According to the Kirby's Adventure instruction manual, the planet is so far away from Earth that it would invisible to Earth's population. Said to be located in Gamble Galaxy in Kirby: Squeak Squad, Popstar is considered by some to be a "backwater planet" in the lore of the Kirby series. This is most notably referenced in the reactions of invaders to Kirby's presence on Popstar (such as that of Susie in Kirby: Planet Robobot), as they often question why such a powerful being lives on this remote planet.
Magolor: Planet Popstar is so amazing.
