Kirby Hub Room is a single-player stage in Super Smash Flash that serves as setting for Target Tests. The stage is composed of tiles from the Rainbow Route of Kirby & the Amazing Mirror, but is a lot more simplistic. All characters have access to this stage when playing through the Target Test, but each character has a different arrangement and position for the targets. Despite the name, it is more a general stage for all characters rather than being Kirby-centered only.
