Digga-Leg

Digga-Leg is a robotic boss from the game Super Mario Galaxy 2. It is fought in the Spin-Dig Galaxy, first in the mission "Digga-Leg's Planet", and later in the mission "Digga-Leg's Daredevil Run" under Daredevil Comet conditions.

Appearance
Digga-Leg resembles a smaller Megaleg, though it has only two legs and its eyes emanate a red glow. Its weak spot is its glass underside, which contains a Power Star. It lets off steam periodically. When the player first encounters it, it slowly activates, then massively lets off steam before attacking.

Combat
Digga-Leg attacks by stomping around the planetoid and creating Diggas, which burrow through the ground's surface and try to harm Mario. Mario can defeat the Diggas 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's in the way.

The only way Mario can defeat Digga-Leg is by using the Spin Drill to burrow through the planet from the position opposite its glass underside. Each time Mario drills into the glass, it will become increasingly cracked. This will only work if Mario starts drilling from the right area of the planet at the right time. If he misfires, he'll either run into one of Digga-Leg's legs or the protected part of its head and be bounced back (with an accompanying clang sound). After Mario cracks Digga-Leg's glass underside three times, it explodes, leaving behind the mission's Power Star.

Trivia

 * Digga-Leg shares its boss music with the Whomp King.

 * Unlike most large enemies, if Mario is hit by its legs, he simply gets knocked away and takes damage instead of getting crushed.
 * Along with Megaleg, Digga-Leg resembles a Snifit.
 * Digga-Leg was originally going to be called "Digg-Leg", but this was changed in the final version of the game.
