Rollodillo

Rollodillo is an armadillo-like boss in the upcoming game Super Mario Galaxy 2. It is fought in the Boulder Bowl Galaxy in the mission "Rock and Rollodillo". Rollodillo is covered in thick blue fur and has a hide made of pieces of rock. He attacks mainly by rolling around the planetoid in a fashion similar to a boulder. Mario can only fight Rollodillo while Rock Mario. When Rollodillo is rolling around, Mario will need to transform into a boulder and ram into Rollodillo. This will cause the boss to reveal its weak spot, its rear. Mario will need to hit Rollodillo's rear three times. After this, the boss will explode and grant Mario the Power Star.
