Dark Octo-Army Romp

Dark Octo-Army Romp is the second mission of the Flash Black Galaxy in Super Mario Galaxy 2. This mission can only be played if the player collected the Comet Medal in the previous mission and when there is a Prankster Comet in orbit. This mission's objective is to defeat thirty Octoombas within a time limit.

After the Prankster Comet has been unlocked, Mario ends up on the Maze Planet. This time, he has to defeat all of the thirty Octoombas within eighty seconds (one minute and twenty seconds). There is a Yoshi egg at the end of the level that may help him defeat the enemies easily. If Mario defeats all of the Octoombas in the time allowed, he earns a Power Star.
