You've finally arrived at the Planet Core, the deepest layer in Donkey Kong Bananza — congratulations! Before we get to that final boss, however, there are some Banandium Gems to collect.

You'll find 23 Banandium Gems in the Planet Core, split between its 10 sublayers. In this guide, we'll be making sure you don't miss out on any of them, with a map and detailed location list for every Gem across every sublayer.

If you still have some Gems left from the previous layers, head over to our Banandium Gem Locations guide hub, where you'll find a similar rundown for every region before this one.

Planet Core Banandium Gem Locations

You'll need to wrap up the main story and come back after the credits for a few of the following Banandium Gems, but you'll be able to pick most of them up on your first run through.

It should go without saying, but this is the final layer in the game, so if you don't want any late-game content spoiling, look away now and come back to this guide once you've wrapped everything else up!

Post-Credit Banandium Gems

There are two more Gems that only unlock once you've polished off the main story and made it through all of the post-credits content.

These last two wrap up the post-credits storyline, so if you haven't made it this far yet, we'd recommend wrapping everything else up before coming back.
