Breaking into the Battlerock

Breaking into the Battlerock is the second mission of the Battlerock Galaxy in Super Mario Galaxy. The objective is to use Bob-ombs and other explosives to enter into the Battlerock itself.

Layout
Like with the previous mission, the player starts off on six small saucers. This time, there are cages and Bob-omb Dispensers, which the player can use the Bob-ombs from to blow up the cages. Inside one of the cages is a Launch Star that will send Mario to a planet with many Chomps rolling on it and a cage with a trapped Luma inside. Bringing a Bob-omb found on the opposite end of the planet, the player can rescue the Luma, which will turn into a Sling Star that will allow the player to reach a Launch Star. The Launch Star will launch Mario to a minefield the player has to use Pull Stars to navigate. Using the Launch Star at the end will launch Mario into the Battlerock itself. A nearby Warp Pipe will take the player to a room where they have to use a Bob-omb to break open a cage and reveal a cannon. Using the cannon, the player can launch themselves into a crystallized Luma. The crystal has two layers, and hitting it anywhere other than the center will just cause the crystal to get smaller, necessitating another cannon shot. Once both layers are destroyed, the released Luma transforms into a Launch Star. Using the Launch Star will cause the Battlerock to explode and send Mario to the final planet. The player has to take a Bob-omb to the other end to break a cage and reveal a cannon. Using the cannon, the player has to time their shot correctly to avoid hitting any obstacles and recover the Power Star.
