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 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, such as using Vanish Luigi to phase through the bars, and Wario can also flatten the stump with a single ground-pound. The Vanish Luigi method is the only non-glitch method that works if the 5 Silver Stars! mission is selected.

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