K. Rool Keep is an adventure stadium in the game Mario Rugby. It is the twelfth stadium in Story Mode.
The stadium is an ice type and is based off of a part of King K. Rool's lair from Donkey Kong Country 2: Diddy Kong's Quest. The course is very rigid and very hard to move across. The course often changes shape and falling ice shards acts as hazards. There are no stands or audiences.
