You can also check out the world map, and the return of the Fire Flower, Bee Mario, and Boo Mario.
Nintendo is on a trailer-releasing spree as they followed up yesterday's Metroid: Other M trailer with a brand new Super Mario Galaxy 2 trailer that shows off a new rock power-up and the new world map.
The trailer shows off the Rock Mario power-up, where Mario rolls up into a ball and zooms around levels. You can do everything from launch off ramps and knock over enemies in a 10-pin bowling formation.
The new world map is also revealed, and features a planetoid spaceship in the shape of Mario's head that looks like it will serve as his means of transportation throughout his next adventure.
There's also appearances by the Fire Flower, Bee, and Boo power-ups, and a new Yoshi power-up that looks like it makes him lighter.
Super Mario Galaxy 2 is due out on May 23.
