At the beginning, immediately start moving right. Jump across to the first tipping platform. Stand on the left side and when the right side rises up, run and jump into a barrel. It will shoot you to a bonus area. Collect a balloon, coins, and bananas so you can walk out with a Puzzle Piece.
After getting into a rocket barrel, fly through the cavern while dodging fireballs. Getting the K KONG letter can be tough, since you must dive under a rock as soon as you get it. Be careful not to dive too much and crash into the lava.
As some fireballs come at you from behind, try to fly in the middle. One of the fireballs will hit a chunk of falling rock and release a Puzzle Piece. Fly right into it and get the Puzzle Piece.
After getting the second Puzzle Piece, fly low over the lava so you can easily get the next Puzzle Piece as well.
When getting the O KONG letter, you must start low to get under a low-hanging rock; then climb up to get the letter and immediately dive down to get under another rock so you don’t crash.
The N KONG letter is low and just above the lava. As soon as you get it, quickly pull up a bit to avoid crashing into some rocks.
After the N KONG letter, collect all of the bananas and a Puzzle Piece will appear in the air in front of you.
This part of the level requires you to dodge leaping flames. The G KONG letter is down low. However, to reach it, you must come in high to avoid being toasted, then drop down to get the letter.
As you enter a narrow cavern, you must dodge hanging rocks as you race against a wall of lava. Collect all of the bananas along the way to make the last Puzzle Piece appear by the rock that rises out of the lava. You will need to climb over the rock, picking up the Puzzle Piece as you do; then dive down so you don’t crash into the low-hanging rock. Continue to the Slot-Machine Barrel to complete the level.
