Rock and Rollodillo

Rock and Rollodillo is the first mission of the Boulder Bowl Galaxy in Super Mario Galaxy 2. This mission introduces the Rock Mushroom power-up. The name of the mission is a pun on the music genre "rock 'n' roll."

Mission
To get the Power Star, the player must first get the Rock Mushroom trapped in a glass cage in the Starting Planet. To do so, they have to defeat the three Elite Octoombas protecting it. After getting the Mushroom, the player will transform into Rock Mario or Luigi, which allows them to roll and break things.

To progress, the player has to use their Rock form to hit the raised bridge and make it fall. Then, they should bowl over the Pinheads and proceed to the next planet. Here, the player has to get to the Launch Star trapped in a glass cage. To do so, they must defeat all the Octoombas found in this planet. When using the Launch Star, the player will find themselves on a planet with a Luma who tells them that if they use the shiny spots on the ground, they will reveal coins and thus regain health. On this planet, the player has to use the Rock Mushroom again and break the giant purple Crystal where the next Launch Star is trapped. After using it, they'll get to an orange crystal planet with a Midway Point, Lumalee, and a Launch Star which blasts them to the Cage Planet.

On this planet, the player will need to fight Rollodillo. After defeating Rollodillo, he will be defeated and leave a Power Star which the player has to get.
