The Crystal Caverns Crystal 1

You will begin this stage in a narrow tunnel. Head down the tunnel and you will enter a room with a barred door on your left and on your right. Grab the fire orb and burn the plank barring the door on your right. Once you enter into the next area, jump across the gap. The first crystal (1/13) is just below the fire orb. Use the fire orb to destroy the giant spider web.

The carts you climb to the fourth crystal

Now, climb up. You will encounter a series of falling platforms. Take the leftmost path. This path will lead you to two crystals (2/13 and 3/13). Once you get to the room the path leads to, you will see some carts filled with dark crystals to your left. Climb them like a set of stairs and acquire another crystal (4/13). You will see a wall of tablets. Hit the tablets until the lines connect. Once you do so, the wall will open up and a treasure chest will be revealed.

The Crystal Caverns Rune 1

From the chest, hop up above and grab another crystal (5/13). Then, use the nearby fire orb to heat the boiler in the next room. This will open a door and grant you access to this stage's first rune (1/4). From here, slide down the rail. Use the fire orb to burn the spider web when you encounter it. Now you will be back in the room from the beginning. Open the other door by burning the plank.

Kao The Kangaroo,  The Crystal Caverns, Grappling After K

There is a lot of tricky platforming here; especially with the grappling section, where you will need to time your grappling according to the moving hooks. After you have swung across the gaps and performed some dark crystal platforming sections, you will end up in a room with some enemies, a boiler, and a stream.

The Crystal Caverns Letter K

Grab the ice orb and freeze the water, then use the wind orb to yank the giant crate. Jump down where the crate was previously. Follow the route until you encounter the letter K. Take the dark crystal platform back to the room from before. Push the crate so that it is under the boiler, grab the fire orb, and ignite said boiler. This will open the nearby chain-link door.

 The Crystal Caverns Crystal 6

Grab the next rune (2/4) and jump on the rail. Ride it to a spider web obstruction. Grab the nearby fire orb and burn it. You will now be back in that first room again. Another set of doors will be open revealing an elevator. Take the elevator down. From here, jump on the railing. You will be dumped in a room with a buff monkey: beat it up. In that room, jump on the stack of crates. There is a crystal (6/13) hovering around in the air just waiting to be grabbed.

Once you have obtained the crystal, break the crates. You will reveal a giant hole in the ground. Jump down and follow that path until you find the 14th Eternal Well.

The Crystal Caverns Heart Piece

Back up to the room. Hit the giant button on the wall. This will open the doors, but don't jump on the trampoline that is revealed! Before you do that, drop down to the right and grab the letter O. Climb back up, and now you can jump on the trampoline. In the next room, there is a heart piece behind a spider web and another rune (3/4). There is also a crystal (7/13) behind some boxes.

 The Crystal Caverns Crystal 8

Burn the plank barring the door, and you will find three crystals directly on this path (8/13, 9/13, and 10/13). Once you reach the area with the beaksters, you will find the letter O behind a giant crate to your left.

The Crystal Caverns Extra Life

Finally, travel along the tracks, grab the extra life, and the next three crystals (11/13, 12/13, and 13/13) will be directly on the main path (with the final crystal being behind a giant test tube). Now, in the final area, you just need to position all the laser towers correctly.

 The Crystal Caverns Laser Puzzle

Just freeze the water and push all the laser turrets around until they are all connected by one continuous laser. Once you do this, you will receive the final rune (4/4). The scroll is off in a side room in this area, so make sure to not complete the stage before grabbing it.
