Banandium Gems in Sublayer 100
The Lagoon Layer’s Sublayer 100 offers 25 Banandium Gems to collect. Right after landing, the first gem is waiting for you immediately in front. You’ll find gems hidden behind dirt walls, inside Ancient Ruins, and even in timed challenges. For example, one gem appears only after you’ve beaten the main story and completed a smashing challenge involving 5,000 cubic meters of water — just spam the X button under waterfalls to achieve this.
Other notable spots include:
- A secret gem behind a soft dirt wall near the Cave by the Cape
- A timed event behind a shiny silver pyramid that requires quick demolition skills
- Battle challenges against groups of Crockoids and Antickoids inside Ancient Ruins
- Hidden niches behind concrete panels and destructible floors inside giant monkey-head caves
- Platforming challenges using Rambi the rhinoceros and floating shifty triangles
These varied challenges mean you’ll have to think creatively and use your Kong Bananza powers wisely to collect them all.

- Timed wall demolition events
- Swimming under villages to reach gems hanging from ceilings
- Traversing thorn-covered paths and secret rooms
- Battles against tougher enemies like Buzzoids and more Crockoids
- Raising water levels to access new areas and gems
After collecting 300 Banandium Gems, the Kong Elder offers a “rehearsal” trial unlocking the final set of post-game bananas. These involve strategic use of boom rocks, baiting enemies, and precise timing in battle scenarios.
