Behind Chain Chomp's Gate

Behind Chain Chomp's Gate (also known as Behind Big Chomp's Gate ) is the sixth mission of Bob-omb Battlefield in Super Mario 64. In Super Mario 64 DS, the mission's name is hyphenated Behind Chain-Chomp's Gate and was moved to the seventh and final mission of the course. The mission's objective is to obtain the Power Star guarded by the titular Chain Chomp.

Layout
The Power Star is visible behind a set of iron bars, which can be removed only by ground-pounding the stump that the Chain Chomp's chain is attached to three times. This frees the Chain Chomp, letting it break the bars and escape. In Super Mario 64 DS, the Star is slightly lower, and its associated mission is unchanged; however, there are a few more methods to obtain the Star. The player can use Vanish Luigi to phase through the bars, and Wario can flatten the stump with a single Ground Pound. The player can also use a Mushroom found inside a Brick Block to flatten the stump. The Vanish Luigi method is the only non-glitch method that works if the mission 5 Silver Stars! is selected.

Through a glitch, it is possible to use an exploding Bob-omb to clip through the gate instead.
