Super Mario Galaxy 2 is a platformer game released in 2010 for the Nintendo Wii. It is the sequel to Super Mario Galaxy. It retains many gameplay elements from its predecessor, but also introduces new ones. As Mario heads to Princess Peach's castle to have cake and watch shooting stars with her, and also meeting a Baby Luma, he sees that Bowser is attacking and has grown gigantic. Bowser captures the princess and plots to take over the universe again. Mario gives chase and ends up on a planet-like spaceship piloted by a Luma named Lubba. It turns out that Bowser had taken the Power Stars he and his crew were using. Lubba gives Mario command of the ship, and they travel through space to find more Power Stars until they can reach the center of the universe and stop Bowser.
If Yoshi eats a Blimp Fruit, he becomes Blimp Yoshi. This makes him inflate and float up to higher places. Yoshi returns to normal if the "Air" meter empties, or if the player shakes the Wii Remote. The Blimp Fruit appears in the Tall Trunk Galaxy, Starshine Beach Galaxy, Flash Black Galaxy, and Bowser's Galaxy Generator.
Hungry Lumas return from the previous game serving the same function. However, they will only turn into galaxies.
There are also Hungry Lumas that eat coins instead of Star Bits. They only turn into planets.
Lumalee also returns with the same function.
She also appears inside the Starship Mario, where she may turn into a Chance Cube.
