Through the Poison Swamp

Through the Poison Swamp is the only mission of the Bubble Breeze Galaxy in Super Mario Galaxy. The mission's objective is to use a large bubble to get around the swamp.

Layout
The player will start on a small island within the swamp. Down the swamp on one of the other islands is a large bubble blower, and the player has to jump into the bubble and use it to navigate around the swamp. Within the swamp are five Star Chips the player has to collect while avoiding Space Mines and using fans to get around. Collecting all the Star Chips will form a Launch Star that will launch Mario to the next area.

The next area has many moving Space Mines and rotating obstacles the player has to navigate through. Along the way, the player may come across ! Switches that will open up a gate for a short time to optional pathways containing coins. At the end of the swap, the Power Star is found in the middle of two circling Space Mines.

Trivia

 * It is possible to skip the second half of the level. The player must go to the south part of the starting platform, then backflip while moving towards the wall. If done correctly, an invisible platform will be under Mario/Luigi. They can then long jump to the right to get the Star.
