In Donkey Kong Bananza, you can smash your way through layers of rocks, concrete, and metal to find literally hundreds upon hundreds of collectibles like Fossils and Banandium Gems, the latter of which is for getting more Skill Points to increase DK's array of abilities.

If you're in the first main layer of Donkey Kong Bananza, Lagoon Layer SL100, you can use this guide to find every single banana (Banandium Gem).

The Banandium Gems in this guide do not include any postgame content.
