Dunk Hammer

Luigi Dunk is a Bros. move in Mario & Luigi: Superstar Saga. Luigi Dunk is taught by Cork and Cask in Chateau de Chucklehuck along with Mini Mario. When Mario whacks Luigi from behind with his Hammer, Luigi will be buried into the ground. While in this state Luigi can move underground, allowing him to pass through obstacles he couldn't before and jump into barrels from beneath. If Luigi passes through an obstacle in which Mario cannot follow, he will be separated. Luigi Dunk can also be used to find Chuckle Beans hidden in underground spots marked with an X. Once Luigi has emerged from the ground, he cannot go underground again without Mario's help. This move resembles Baby Drill from Mario & Luigi: Partners in Time and Drill Bros. from Mario & Luigi: Bowser's Inside Story.

In Mario & Luigi: Dream Team, this move returns, but this time Mario is the one dunked, so the move is called Mole Mario.
