Mario has a brand new suit in Super Mario Galaxy 2. When Mario touches a Rock Mushroom he can transform into a giant boulder and roll over enemies.
Power ups from previous games – Bee Suit, Ghost Mario, Fire Flower, and Yoshi also return in Super Mario Galaxy 2. Yoshi, like Mario, has new tricks such as a Dash Pepper powered wall running and inflating like a balloon when he eats a Blimp Fruit. See screenshots of those below.
