Battlerock's Garbage Dump

Battlerock's Garbage Dump is the sixth mission of the Battlerock Galaxy in Super Mario Galaxy.

Layout
This mission takes place during the Breaking into the Battlerock mission. Before using the first Launch Star, the player should collect the Star Bits under the saucers and in the cages, which can be broken by throwing Bob-ombs at them. On the next planet, there is a Hungry Luma that asks the player to feed it thirty Star Bits, the exact amount that can be found on the previous saucers. Feeding it the amount asked will have the Luma transform into a pink Launch Star that will take the player to a new area.

Upon landing on the new platform, a Gearmo will tell the player that he's angry at others for dumping their trash here. He then asks the player to help him get rid of it all by blowing it all up with Bob-ombs, and accepting will start a timer of thirty seconds. Since the Bob-ombs take ten seconds to explode, the player must position them carefully; there are yellow circles amongst the platform that hint toward the best positions for the Bob-ombs to be thrown. By blowing up all the trash within the time limit, the Gearmo will thank the player's help with a Power Star, though unlike other challenges which result in a lost life if the player fails, they won't here, here they can try again as many times as they want until they win. The trash somehow comes back when they fail the challenge where they have to blow it all up again.
