Throwback Galaxy

The Throwback Galaxy is a galaxy from Super Mario Galaxy 2 which is a redesigned Whomp's Fortress from Super Mario 64. The music is an orchestrated arrangement of the original Super Mario 64 main theme, as the original version was also played on Whomp's Fortress. Although the course is generally identical, a few minor changes have been made here and there. New enemies have been added, such as Paragoombas, Skeeters and a Wiggler. Other enemies seen first in the original game also return like Piranha Plants, Thwomps and Whomps. Some Bob-omb Buddies also appear in the galaxy, and even make reference to how Mario seems familiar, a reference to his earlier visit to Whomp's Fortress in Super Mario 64 and its remake. A Whomp is found at the top of the area, and defeating it will open an area where the Whomp King is found. A Comet Medal, Rainbow Notes (released from breaking a crate, playing the Super Mario Bros. underground theme) and a bonus planet featuring Piranha Plants can be found in the stage too. Several Cloud Flowers also appear in the galaxy's second mission.

Return of 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. Now, when the player gets to the top, he/she fights 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. Upon defeating this Whomp, however, a hole opens up in the center of the platform, which the player must then drop down to get to the planet's underside, where the player fights the now even bigger and tougher Whomp King. The area he will slam down on is now highlighted in red, and the player can walk up his legs. The Whomp King also has some new attacks. One is where he does a short hop, which will stun Mario or Luigi if they are on the ground. A second is when he stomps his right foot down, and some miniature Whomps come out of the ground. The player should Ground Pound an imprint on his back three times, where he will utter the same dialogue 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 Star.

Silver Stars in the Whomp Fortress
There are Cloud Flowers and 5 Silver Stars added in this level. With the help of the Cloud Flower, Mario/Luigi needs to get all the Silver Stars in the galaxy, so he is rewarded with a Power Star. The Whomp which defeated leads to Whomp King is replaced with two Paragoombas.

Whomp Silver Star Speed Run
This is Throwback Galaxy's Prankster Comet. The stage is the same as Silver Stars in the Whomp Fortress, only there is a time limit of two minutes. If Mario or Luigi grab the five Silver Stars before the time ends, they gain a Power Star.
