Return of the Whomp King

Return of the Whomp King is the first mission of the Throwback Galaxy in Super Mario Galaxy 2. The mission's objective is to defeat the Whomp King.

The first mission here is very reminiscent of the same mission in Super Mario 64 and its DS remake, with a few minor changes. When Mario gets to the top, he battles a regular Whomp, which, due to the size changes in the species between Super Mario 64 and Super Mario Galaxy 2, appears to be more or less identical to the original Whomp King in size. The biggest difference between "Chip off Whomp's Block" and this mission is, upon defeating this Whomp, a hole opens up in the center of the platform, which Mario must then drop down to get to the planet's underside, where the player fights the now even bigger and much tougher Whomp King.

His size is much larger than before, due to the fact that normal Whomps are about the size that he was in Super Mario 64. Because of his size, he also can walk around the battlefield much more quickly than before. The area he slams down on is now highlighted in red. The Whomp King also has some new attacks, which also make him more difficult. For one attack, he does a short hop, which stuns Mario or Luigi if they are on the ground. This shockwave also occurs when he slams down as his primary attack. A second is when he stomps his right foot down, and a group of Pattans appear from the ground. He is harder to get on top of, as his increased thickness makes the flat surface of his back higher up than it used to be, so Mario will likely have more trouble getting the chance to attack him than before. Instead of being able to Ground Pound anywhere on his back to damage him, the player must hit the Ground Pound logo on his back (similar to the rest of his species). Additionally, Mario cannot go through the Whomp King's body, and he can fall off the arena. When defeated, he recites the same speech as in the original Super Mario 64, as well as then hitting the ground while muttering "Dang it!" under his breath, before exploding and handing over the Power Star.
