Digga-Leg

Digga-Leg is a robotic boss from the game Super Mario Galaxy 2. It is fought in the Spin-Dig Galaxy in the mission "Digga-Leg's Planet".

Appearance
It resembles a smaller Megaleg with its weak spot being on its glass underside, containing a Power Star. However, it only has two legs and its eyes emanate a red glow.

Strategy
The only way to defeat Digga-Leg is for Mario to drill through the planet from the opposite position of its glass underside to puncture it. Digga-Leg attacks mainly by stomping around the planetoid. It will also summon Diggas. The player can defeat the yellow drill-creatures by stomping on their heads or by drilling under them.

When angered, Digga-Leg will jump high into the air and come plummeting down, damaging Mario if he was in the way. After being hit three times with the drill on the underside, the boss succumbs, explodes, and grants Mario the level's Power Star.

The player faces Digga-Leg twice, with the second fight being under the Daredevil Comet conditions.

Trivia

 * Digga-Leg shares the same boss theme as Whomp King.
 * Oddly enough, Digga-Leg is actually a bigger and evolved form of Digga.
