Digga

Diggas are Bullet Bill-like enemies appearing in Super Mario Galaxy 2; they are first located in the Spin-Dig Galaxy. Diggas are similar to Drill Moles from Super Mario Land 2: 6 Golden Coins, only instead of burrowing underground and attacking Mario, Diggas drill with their body exposed and ignore Mario. They have a yellow body, a drill for a nose, angry eyes, and no arms or legs. They can be easily destroyed by a Jump or with a Spin Drill. They can also be summoned by the boss Digga-Leg.

Trivia

 * In Super Smash Bros. Brawl, an assistant trophy features a Rabbit Shaped girl with a Spin Drill that had the same attack pattern as a Digga.
