Mountain Mania

Mountain Mania is the tenth level in Donkey Kong Country: Tropical Freeze and its Nintendo Switch port of the same name and the second level of Autumn Heights. It takes place in a mountainous area, hence the name, and features several small towers with bells. It is the first level to have Rambi the Rhino.

Overview
Donkey Kong and Diddy Kong start in an area similar to the end of Windmill Hills, and soon after, there is a barrel to bring in Dixie Kong as DK's partner. There is also a large stone block with Rambi's symbol on it under the platform. After the two go through an area with Fluffs and a Cheesy Chester, the Kongs can break an animal crate to free Rambi, who can smash through objects such as spikes and weak structures. After going through an area with enemies such as Waldoughs, Rambi, DK, and Dixie will go through a series of Barrel Cannons to a similar area where there is a checkpoint and some structures with bells that Rambi can break with his horn to release bananas.

After that is another checkpoint and a platform which the Rambi and the Kongs can stomp on to reveal a Barrel Cannon that brings them to another large area with several wood bridges, which can be destroyed by the volcano fire and enemies such as Cheesy Chesters, Walbricks, and Blue Hootzes. After the third checkpoint, there is a rocky area with the above surface descending and more stone blocks, which must be smashed by Rambi to get through and avoid being crushed by the falling rock. After this, there is a short area with platforms and more stone blocks, and at the end, there is the Slot Machine Barrel.
