Breaking into Bowser's Castle

Breaking into Bowser's Castle is the first mission of Bowser's Gravity Gauntlet in Super Mario Galaxy 2. The objective is to defeat Bowser.

Mission
First, Mario lands on Bowser's Castle. He needs to pass a Dry Bones, four Lava Bubbles and a Fire Bar. Mario then gets on a metal platform and the gravity changes, and there is a Magikoopa. Then the gravity changes and Mario avoids eight Fire Bars. A Life Mushroom can be found on the corner. The gravity changes again and again until Mario enters the castle. Mario can find a Checkpoint Flag here. On top of a Brick Block, Mario can find the Comet Medal. After the gravity changes four more times, Mario enters some water. Enemies in the water include Cheep Cheeps and Fire Bars. When Mario exits the water, there is another Checkpoint. Above it Mario can find a 1-Up Mushroom. The gravity changes and Mario comes to two Whomps. The gravity changes again and Mario finds a Fire Bar Spinning Platform, and a Launch Star. The player comes to the Big Door Planet. Mario needs to jump onto the Meteors and Ground Pound them into the locks. The door draws Mario in and he end up on the Bowser Throne Planet.

Upon arrival, Bowser does not seem to be present. Luma is puzzled and looks around for him, but then grumble is heard, and Bowser appears, initiating the battle. To defeat him, Mario must hit him with a Meteor four times, much like the previous battle. However, this time both Bowser's pound attack and the falling of the meteors produces a shock wave whey they hit. Once defeated, he loses another Grand Star and shrinks back to regular size. As he escapes again, Mario obtains the fourth Grand Star and travels back to Starship Mario, where the portal to World 5 is opened.
