Planet Wisp (Wii)
From Sonic Retro
Planet Wisp is a level in the game Sonic Colours.
What has been shown of this zone so far eludes it to being a industrial level built into a mountainside, leaving plenty of room for jumps through the twisting metal around mountains. The name of the level seems to show that this is the Wisps homeworld, where Eggman must have captured them to fuel his interstellar theme park.
