Toy Time Galaxy

Toy Time Galaxy is a galaxy in Super Mario Galaxy. It is a location filled with toys that are made out of rainbow building blocks, presumedly acting as platforms. Colorful trains have been seen there. The Spring Mushroom is found here. Cosmic Koopas also appears here. This Galaxy is located in the Engine Room Dome. This Galaxy is inhabited by Gearmos (like the one in the Battlerock Galaxy). The galaxy has a planet that is an homage to Mario and Luigi (Mario on one side and Luigi on the reverse side.)

Heavy-Metal Mecha Bowser
Mario must traverse the galaxy until he gets to a giant toy robot, where Mario must take it appart, peice by peice, while avoiding traps, until he takes apart the head, releasing the Power Star.

Mario Meets Mario
Mario heads to the 8-bit size Mario planet to collect five Silver Power Stars. The red pixels on Mario are replaced by lava, shrinking, and turning squares. The player must carefully and quickly make their way around the planet to collect the five silver stars and then make it back to the beginning to collect the power star, which is difficult as each tile they step on will disappear.

Luigi's Purple Coins
This is a very difficult level in which the player must collect 100 of the 150 purple coins on reverse side of the 8-bit Mario planet, which looks like 8-bit Luigi, within a time limit. The pixels are replaced with dark matter, turning squares, and shrinking squares. If they collect 100 purple coins, they must make it back to the start to collect the power star.
