Spooky Cosmic Clone Chase

Spooky Cosmic Clone Chase is the third mission of the Haunty Halls Galaxy in Super Mario Galaxy 2. This mission can only be played if the Comet Medal was collected during the first mission and while a Prankster Comet is in orbit.

Mission
The player starts at the beginning of the Creepy Corridor Planet, with a long path moving against the player and Mattermouths eating away at it. Once the player steps onto the path, Cosmic Clones start appearing. The area is mostly the same as it was in the previous mission, though the Big Boo does not appear at the end and the Power Star is trapped in a large crystal.
