Rainforest Rumble

Rainforest Rumble is the thirty-fourth level in the classic Game Boy and Game Boy Color game, Donkey Kong Land III. It is also the fourth area of The Lost World.

This is the game's final rain forest level, and unlike other rain forest levels, it does not involve the Kongs sliding along moving vines. In fact, throughout the level, the monkeys will be turned into the Animal Friend, Ellie the Elephant. This ally will have to travel through much of the stage. Though one of the last levels in the game, Rainforest Rumble is a more generic stage, and does not feature any special hazards. It is, however, filled with many small gaps for Ellie to jump over, as well as an abundant number of foes. Of these enemies are Bristles, Buzzes, Sneeks, Krimps, and a lone Krumple. A few Knik-Knaks also appear in a hidden area of the level. Many of the level's Buzzes are located around abysses to attack the heroes.

Level layout
From the start of the level, the heroes have to head east and run into a barrel. This barrel blasts them over an abyss and into an Animal Barrel, turning the monkeys into Ellie the Elephant. From there, the transformed group must walk down a long path, filled with many small gaps. As Ellie jumps over each abyss, she has to watch out for many enemies, mainly Sneeks and Buzzes around the pits. On the way, the elephant runs into the letter K and has to hop over more gaps. After jumping across a rather wide abyss, Ellie finds the letter O. At that point, she must defeat more enemies with her water-shooting abilities and cross two small gaps to find the Star Barrel.

Now about halfway through the level, the Animal Friend has to travel over more abysses. She also meets some Krimps around the area. On a small platform, she can find the letter N. After this, the small elephant needs to avoid more enemies and cross more pits to find the letter G in plain sight. After this is collected, Ellie has to cross another abyss and walk down a long, enemy covered path to find a No Animal Sign. Once this sign is passed, Ellie turns back into the Kongs. At that point, the heroes must jump into a Rotatable Barrel and blast to a Krumple on the other end of an abyss. There, they encounter the flagpole. Once they touch it, the level will end.

Bonus Levels

 * At the beginning of the level, the heroes must travel west and drop off of the cliff to land in an Animal Barrel. It turns them into Squawks the Parrot. The bird must be used to fly over a wide abyss. On the other end of the abyss, the parrot crosses a No Animal Sign to turn back into the Kongs. Nearby will be the Bonus Barrel. The heroes have to jump inside it to begin the special Bonus Level. There, they need to jump into another barrel and shoot through a long chain of other barrels, collecting a few stars At the end of the stage, the monkeys will be shot into the Bonus Coin.
 * At the end of the level, the Kongs will get in a Rotatable Barrel. They need to aim the barrel into an abyss below them and fall downwards. They will be caught by a Bonus Barrel and then enter a Bonus Level, where they need to race along a few long tightropes to grab stars. Time is short, however, so the monkeys must act fast. Once all the stars are collected, the Bonus Coin appears in the bottom-right corner of the area.

DK Coin

 * At the end of the level, the heroes will notice a lone barrel sitting in front of the flagpole. The monkeys have to pick it up and jump over the flagpole to find a Koin with the DK Coin. The heroes have to defeat the foe to get the coin, but he uses a shield to block all their attacks. So, the group needs to jump on top of him and throw the barrel they found at the edge of the screen. The barrel will bounce back and hit the Koin's side, defeating him, and also giving the apes the DK Coin.
