Unlocking the Groove Layer and Swap Harp
The Groove Layer is where you bring the music back to life in the disco hall. After restoring the bass source, you can purchase the Swap Harp from the Constructone for 500 gold. This harp lets you switch materials between rubber and gold, which is key to accessing many hidden gems. Remember, some gems only appear or become collectible after defeating the layer’s boss and regaining your Bananza powers—like the elephant’s suction and chunk abilities or the snake’s charge jump.
Top Banandium Gem Spots to Explore
Here are some of the most notable Banandium Gem locations you won’t want to miss:
#1: The Secret in the Solitary
Head back to the jail after restoring the bass source, buy the Swap Harp, and use it to turn your jail cell door to gold so you can break it open. Navigate through the hallway and dive punch on the largest rubber bananas to reach the ceiling where the gem awaits.
#2: Deep under Detention
In the Disco Hall, swap the rubber ground near the large triangular speaker to gold and break it to access a barrel leading to a lower segment. Dig carefully past hidden explosives to uncover a banana at the end of the tunnel.
#3: Banana behind Bars
Grab a gold chunk from the jail’s top floor, drop to the second level, and throw it at the concrete bars to enter and collect the banana inside.
#7: Over the Disco
After restoring the bass, use a rubber Fractone as a bounce pad to dive punch your way up to the banana perched atop the disco ball. Holding down the A button helps reach higher elevations.
#10 and #11: Challenge Course Bananas
Unlock the challenge course by swapping the barrier to gold. Halfway through, you’ll find a gem, and another awaits at the course’s end. Prepare for some tricky platforming!
#13: Cranky’s Groove Rant
Enter the VIP room after opening its door by destroying a transforming steel Fractone. Listen to Cranky Kong’s speech to earn a banana reward.
#17: Disco-Ball Destruction
Free a Fractone locked in jail by swapping its cell door to gold. After returning to the VIP room, unlock the terrace, jump into the cannon, and blast yourself at the disco ball to find a hidden banana.
Additional Tips for Collecting Banandium Gems
Many Banandium Gems require you to revisit areas after progressing in the story or beating the main layer boss. Keep an eye out for subtle hints like new passages opening or changes in the environment, such as holes appearing where speakers once stood. Using your Bananza powers strategically reduces the need for constant material swapping and makes traversal smoother.
