This level is more like a collection of dangerous bonus areas. You need to clear out all the coins in order to collect the Puzzle Piece. Start off by moving to the DK platform and then jumping into a barrel that will take you to the first challenge.
Here you must get all five coins while not getting hit by the Tiki Zings moving around this area. Time your jumps carefully to miss the enemies, since you want to avoid taking any damage this early in the level.
This challenge requires you to jump among four platforms while avoiding being smashed by Screaming Pillars. Watch the Screaming Pillars in the background so you can see which are falling and which platform will be safe to jump to. After five coins have appeared, the Screaming Pillars will stop falling. Get the last coin and then jump up and get the Puzzle Piece.
At the next area, you must get onto some high platforms using Squiddles as stairs. As one comes toward you, jump onto it, hitting the jump button just as you make contact so you can jump onto another one. Do this until you reach the platforms. Collect the five coins at the top to make the next Puzzle Piece appear. Pick it up and then blast to the next area.
The next challenge places you on a giant rotating wheel. Follow it around, collecting coins while avoiding the Buzzbites. This gets tougher as the outer ring of the wheel begins to speed up as it rotates in the opposite direction as the center wheel on which you are walking. Be careful not to get too far to one side or you may fall off.
If you thought the previous challenges were tough, this is even harder. You must jump between two platforms while avoiding waves of spiky boulders that come down on you. After each wave, a gold coin flies up between the two platforms. Jump over and catch it before it drops down again. After you get five coins, the Puzzle Piece appears. Get it.
After you grab the final Puzzle Piece, jump into the barrel and shoot to the final chamber to collect the org.
