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
In Super Mario 64, the Power Star is behind some 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. The Star in Super Mario 64 DS is located in the same place and can be collected in the same way, but there are several alternatives to getting this Star. This includes using Vanish Luigi to phase through the bars, ground-pounding the peg a single time as Wario, or collecting the Star during 5 Silver Stars! using Vanish Luigi when the Chain-Chomp relocates to the adjacent field.

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

Trivia

 * In Super Mario 64, a higher jump is required to collect the Star, since it is too high to collect with a normal one; in Super Mario 64 DS, this has been changed so that a normal jump can be used.
