Donkey Kong Bananza takes players on an exciting adventure through the Underground World, where DK must explore multiple layers, overcome challenges, and collect valuable Banandium Gems to power up his abilities. While gathering every gem isn’t required, securing as many as possible will make the journey smoother.
In the
Lagoon Layer SL102, players will find fewer collectibles compared to previous areas, offering a brief respite before diving deeper into the
Planet Core. If you're searching for every hidden
Banandium Gem in this sublayer, this guide will help you locate all five without missing a single one.
All Banandium Gem Locations in Lagoon Layer SL102
Banandium Gem #51 – Dipped Into Chimpy Channel!
As soon as you enter
SL102, you’ll unlock the
Kong Bananza transformation. Use this new ability to smash through obstacles in the starting area, where you’ll find a
bundle of three Banandium Gems waiting to be collected.
Banandium Gem #52 – Pop And Destroy
This gem is tied to the
Pop Party Challenge Course 3, where you must locate and pop
five hidden balloons. The first four are easy to spot, but the fifth one is cleverly concealed.
- Look for a rotating platform in the challenge area.
- Press B to make DK slam downward, revealing a hidden underground room.
- Inside, you’ll find the last balloon—pop it to unlock Banandium Gem #52.
Banandium Gem #53 – Atop The Concrete Roof
Still in the Pop Party Challenge Course 3, the second gem is perched on the roof of the challenge room.
- Break through the walls leading outside the main area.
- Climb the concrete walls surrounding the structure.
- At the very top, you’ll discover Banandium Gem #53.
Banandium Gem #54 – Hung From The Ceiling
This one is easy to miss due to its unusual placement. While searching for balloons, look up at the ceiling of the challenge room.
- Spot the gem dangling from above.
- Use the metal platforms to jump and grab Banandium Gem #54.
Banandium Gem #55 – Shipwrecked Treasure
The final gem in SL102 requires some exploration outside the challenge area.
- After completing Pop Party Challenge Course 3, head in the opposite direction of the room.
- Break through a hidden wall to uncover a wrecked ship.
- Navigate to the far side of the shipwreck to find Banandium Gem #55 near an opening.
Final Tips for Collecting Banandium Gems
- Use Kong Bananza’s abilities to break through obstacles.
- Check hidden areas by slamming the ground or climbing walls.
- Always look up—some gems are placed in high or hard-to-see spots.
By following this guide, you’ll secure every Banandium Gem in Lagoon Layer SL102, boosting DK’s strength before the next phase of his adventure. Stay tuned for more Donkey Kong Bananza collectible guides as you journey deeper into the Underground World!
