List of Contents

Go to the Planet Core layer and fast travel to the Entry to the Heart of Gold. Approach the Banandium Root and select "Get a song idea?".
Speak with one of the Lil' Eelevators after in order for Great Harmoneel to appear.

Transform into Ostrich Bananza form and drop egg bombs on the thorns to clear them away.
Land on the golden floor and change into Snake Bananza form. Use Charge Jump and change into Ostrich Bananza form in mid-air to glide across the path.

Move around the spiky ball path carefully. Destroy the rock with a red shine coming out of it to get an Apple and restore health.
If you still have some Bananergy left, you can transform into Kong Bananza form to destroy the concrete and skip crossing the path that has the spiky balls.
You can find the first Banandium Gem (Halfway through the Harmoneel) at the end of the elevator section where multiple enemies surround the area as you go down.
The next section requires you to ride the green terrain, tear off a chunk of it, and smash the wall with it all while avoiding the concrete enemies from approaching you.
Once you reach the end of the path, grab a chunk of the green terrain to activate the device in the middle to open the next area. Avoid fighting the scorpion enemies that spawn after.
Tear off a chunk of the floor and use it to hit the concrete NPC. Pick up a piece of the concrete and turf surf towards the railing.
Jump to avoid the enemies on the railing and enter the barrel to proceed to the next area.
If you want to get the balloon, you need to use the concrete from the NPC and repeatedly jump to avoid whittling it down as you ride the railing. Jump over the barrel and make your way up the railing to reach the balloon.

Transform into Kong Bananza form and destroy the concrete walls as you make your way down. Once you reach the bottom part of the side-scrolling section, transform into Zebra Bananza form to outrun the flaming barrels.
Transform into Zebra Bananaza form and dash through the water while avoiding the flaming barrels. Ride the minecart to reach the final area.

The second Banandium Gem (End of the Harmoneel) can be found at the end of the area after riding the minecart.
You can find this balloon by progressing through the area covered in spiked vegetation. You will need to use the Snake Bananza Form to jump high, and Ostrich Bananza Form to glide towards the balloon.
This balloon can be found inside one of the spiked platforms, where spiked metal balls are descending down the path. Use the Kong Bananza Form to quickly smash through the wall.
You can find this balloon floating in the area where moving platforms are steadily progressing beside purple stomping enemies. Use the Snake Bananza Form to reach the height where the balloon is floating.
You can find this balloon when progressing the sky rail part of the course. Avoid the obstacles blocking your path to reach the area where the balloon is floating.
This balloon can be found in the area where flaming barrels are descending down on the course. Use the Snake Bananza Form to slow down the barrels by using Glare.

Completing the Great Harmoneel's Final Rehearsal unlocks the secret ending of Donkey Kong Bananza. After completing the rehearsal, you will receive the objective to head to the surface.
Approach the Banandium Root south of the Great Haromneel and select "Go to the surface!".

For the rail grinding part, you can just get one of the scorpions from the previous room so you don't have to jump constantly or worry about the rock breaking
