There are multiple challenge courses in each layer of Donkey Kong Bananza, and Stompy Ascent is one of the most challenging levels in the Canyon Layer. This Donkey Kong Bananza challenge course is located along the main path through the Canyon Layer, so most players will encounter it on their journey to the planet's core.

There are three Banandium Gems to collect in this challenge course, but one of them is well hidden and hard to find unless you're paying close attention during the level. There are several stomping enemies throughout this challenge course (hence the name), and they can make it hard to focus and hunt down any hidden bananas. Here's where you can find all three Banandium Gems in the Stompy Ascent challenge course in Donkey Kong Bananza.

Stompy Ascent Banana #1

Donkey Kong Bananza Stompy Ascent Banana 1

The first Stompy Ascent Banandium Gem is hidden behind a destructible wall near the beginning of the level. To reach it, climb onto the first elevator platform and take it halfway up. The entire wall ahead is made of metal spikes, except for a breakable part in the center. Avoid the stomping enemies and punch through the wall's weak spot to reveal the banana. Once you've gotten it, use the barrel inside to launch yourself to the top of the wall.

Stompy Ascent Banana #2

Donkey Kong Bananza Stompy Ascent Banana 2

The second Banandium Gem in Stompy Ascent is located halfway through the course. It's sitting out in the open past the first elevator platform, so you can't miss it. Smack it a few times to collect it, then continue forward to the second elevator.

Stompy Ascent Banana #3

Donkey Kong Bananza Stompy Ascent Banana 3

The third and final Stompy Ascent Banandium Gem is located at the end of the course. It's waiting for you at the exit near the barrel at the top of the second elevator, but reaching it is a challenge. Carefully cross the gap, destroying the thorns and avoiding the stomping enemies along the way, then ride the elevator platform all the way to the top.

There are a bunch of stomping enemies on the second elevator ride, and they can destroy the platform if you're not careful. Rip off a chunk of stone to defend yourself, and try to bait the stomping enemies into attacking parts of the platform that you're not using. Once you reach the top of the wall, you can claim the final Banandium Gem.

You can use these three Banandium Gems to upgrade DK's abilities in preparation for the upcoming Donkey Kong Bananza sublayers. Things only get more difficult from here, and the environments get much harder to destroy, too. Make sure to check out the other Canyon Layer challenges and stock up on as many bananas as you can before moving on.
