|Chain Chomp||Valley||A chained creature with traits of a dog. It tries to bite Mario, but being chained at a pole doesn't let him attack from far. Free him by ground pounding the pole into the ground... if you dare at least. But don't worry. When freed, it goes away.|

|Mr. I||Horror||An eyeball with stares at Mario the whole time and shoot lasers. Encircling the creature 3 times in a row would defeat it (since it's not a 3D game, Mario must jump, duck, fall and run). Even rotating platforms would help if a Mr. I sits in the middle of the rotating platforms.|
|Broozer||Undead||When it sees Mario, it tries to crush him by punching in his face. Using three stomps or a Ground Pound defeats it.
Broozers could crush any kind of block, so they must be used in a few puzzles.
