Chain Chomp
Chain Chomp is an enemy that appears only in BoB. He is chained to a wooden post, and he lunges at Mario when he is nearby.

If Mario ground pounds on the post 3 times to put it into the ground, Chain Chomp becomes freed. It activates a cutscene where chain chomp jumps around, smashes the gate that has a star behind it, and then jumps up the mountain. Chain Chomp then disappears, and gameplay resumes.
Glitches
Chain Chomp Falls Down
The exact cause is not known, but sometimes during Chain Chomp's cutscene he will fall off past the fence, which causes his animation to glitch and he doesn't jump to the right places.
Huge Chain Chomp Jump
When Chain Chomp touches a Bob-omb or a Cork Box, he will fly into the air. Usually his chain keeps him from going very high, but if he touches a cork box or bob-omb during his cutscene, there is nothing to stop him and he flies very high into the air before landing again. After landing, he resumes his cutscene as normal.
Interruption Softlock
If Chain Chomp touches a thrown cork box during his cutscene, after he flies into the air and lands again, he will not resume his cutscene, resulting in a softlock.
Pivot Clone
The pivot point where Chain Chomp is chained to is an invisible object that loads and unloads when Mario goes close to it and away from it. This means it can be cloned. Releasing a clone of chain chomp's pivot will cause him to move to there.
When Mario goes away from Chain Chomp's new location, Chain Chomp will disappear. Chain Chomp will reappear when Mario goes back to the new spot, but he will appear at his normal location. From then on he behaves normally.
If Mario ground pounds the post while Chain Chomp is visible at his new location, the chain chomp will start his animation at his new location.
If Mario moves chain chomp away from his post with a pivot clone, makes him disappear, and ground pounds the post while Chain Chomp is invisible, then the cutscene does not activate until Chain Chomp is reloaded by going to his new location and Mario touches the ground.
Chain Chomp's pivot is invisible, and since it is not rendered it does not update the HOLP. In order to release it at a specific location, it is usually required to use a preset HOLP and a glitch such as Hat in Hand to prevent the HOLP from updating during the cloning process.
Out of Bounds Softlock
Chain Chomp has no collision with walls, so by moving him near a wall with a pivot clone he can easily become out of bounds. If his cutscene is activated by grounding his post, he will fall underneath the course until he reaches the default water at Y -11,000. Then he will stay at the surface of the water and not move. Since he never finishes his cutscene, this results in a softlock.
Conflicting Cutscene Glitches
Chain Chomp's cutscene can conflict with other cutscenes, resulting in unintended results.
Big Bob-Omb Defeat Cutscene
If Chain Chomp is moved to a new location with a pivot clone, deactivated, and has his post pounded, then his cutscene can be activated at any time by going near his new location.
If the player defeats the Big Bob-omb, but then jumps down to the Chain Chomp to activate his cutscene at the same time, the Big Bob-Omb's textbox plays first, and his star appears before the Chain Chomp does anything.
After this, Mario can move around even though Chain Chomp is freed. Chain Chomp doesn't actually start his jumping cutscene unless Mario stands still for a few seconds, but Mario can still move around once it starts.
Chain Chomp still has an active hurtbox during his cutscene.
