Infiltrating the Dreadnought

Infiltrating the Dreadnought is the first mission of the Dreadnought Galaxy in Super Mario Galaxy.

Layout
The player starts on the hourglass-shaped Beam Planet surrounded Eye Beamers whose laser beams will damage Mario. The Space Fantasy music plays. Moving to the top of the planet, the player can use a Spring Vault as a spring to reach a Launch Star, which will send the player to a small area with three Goombeetles. Defeating all three Goombeetles will open up a Warp Pipe that leads into the Dreadnought. In this two-dimensional platforming section, the Space Athletic music plays. The player has to Wall Jump up moving walls and avoid getting squashed by rising platforms. Spinning the Arrow Switch at the end will flip the gravity to allow the player to walk on the wall, where the player then has to avoid the same rising platforms by Wall Jumping up them at the proper times. Then, the player has to avoid cannonballs and flip another Arrow Switch to change the gravity to the ceiling. Using a springboard, the player has to time a jump through two walls and avoid the cannonballs, then use two Spring Vaults to reach a Warp Pipe, leading outside of the Dreadnought.

The Warp Pipe will take the player to a Tower Planet with Bob-ombs and Topmen. The Battlerock/Dreadnought music plays on this planet. Using the Topmen as springs, the player has to climb up the rotating tower and Wall Jump up two walls as they rise to reach a Launch Star. Upon landing on the next planet, electric beams will become active. The Sling Star on the opposite side will take the player to the next planet where the Space Fantasy music plays, and the player has to lead a Bullet Bill to a cage that is blocking the flow of water. Breaking the cage will cause the planet to fill with water and Eye Beamers will start to search the planet, and the music changes back to the Battlerock/Dreadnought music. The player has to use platform side of the Eye Beamers to navigate around the planet, eventually leading to the Power Star.

Trivia

 * This is one of the missions where the Battlerock Galaxy theme and the Space Fantasy theme switch between each other. The Battlerock Galaxy theme plays at the Tower Planet and Aqua Planet (After being flooded with water), while the Space Fantasy theme plays at the Beam Planet, the entrance to the interior of the Dreadnought, Blue Cube Planet and Aqua Planet (Before being flooded with water). Additionally, the Space Athletic theme also plays inside the Dreadnought.
