Rock Mushroom

Rock Mushrooms are power-up items in Super Mario Galaxy 2. They transform Mario into Rock Mario, (Luigi into Rock Luigi) and when collected, Mario's hat and overalls turn into stone, and it gives Mario the ability to encase himself in a boulder upon shaking the Wii Remote once.
In this form, Mario can roll around, jump, damage enemies, and destroy red crystals with items in them. However, when he comes into contact with a crystal or a certain type of enemy, he will revert to his rock form. However, players can almost always return to his boulder form by re-shaking the Wii Remote or pressing Z on the nunchuck. In Melty Monster Galaxy's A Stroll Down Rolling Lane, there is a special Rock Mushroom, and with it, Mario will do a spin if Z is pressed or if the Wii Remote is shook instead of reverting to normal. In either scenario, Mario will revert to his normal form if he takes damage or touches a Launch Star.
The Rock Mushroom is of paramount importance in the Boulder Bowl Galaxy, and in the second mission of Melty Monster Galaxy.
