Durian Kingdom

The Durian Kingdom is the twelfth kingdom in Donkey Kong Jungle Beat and the fourth kingdom linked to the J Barrel. This kingdom is characterized as a fortified mountain. The Durian Kingdom can be accessed by completing all the kingdoms in the K Barrel and collecting 18 Crests. The Durian Kingdom is the dominion of Ninja Kong and Ninjapes. Donkey Kong travels through this kingdom to fight the mighty Ninja Kong, and at the end of every level he eats a giant durian.

Battle for Storm Hill
Battle for Storm Hill is the first area of the Durian Kingdom. In this level, Donkey Kong ascends to the top of Storm Hill. Cannonballs rain from the sky here, and they can easily hit the ape if he is not careful. Many Ninjapes also appear here and use a variety of attacks to slow down Donkey Kong, such as throwing shuriken, manning cannons, and directly fighting him. There is a fort in the level as well, and Donkey Kong must avoid the many Tusk enemies to climb it safely. Once Donkey Kong bites into the giant durian at the end of the level, the ape heads on to Aerie Fortress.

Level Layout
At the beginning of this level, there is a a group of three strange flowers placed near Donkey Kong. If they are hit by his Sound Wave Attack, they can give the ape some bananas. The path ahead is very barren, but has some cannonballs falling towards it. Enemies also cover the straight pathway to steal beats from the ape. The bland and empty pathway eventually leads the Kong to some Ninjapes. After the ape heads down a small, but steep, hill, a fast, yellow Hawg enemy begins to dash towards him. Once the enemy is defeated, the ape can continue down the barren area, fighting more black Ninjapes on the way. As the Kong progresses, the path becomes more flattened, and another yellow Hawg rushes into him. Once the foe is defeated, Donkey Kong can head over some small hills, passing a small Roc enemy on the way. More Ninjapes are farther ahead of here, along with a lone green Ninjape. This foe can be followed into a tall fort. At the entrance of the fort, there is a small Tusk enemy being controlled by a red Ninjape. Donkey Kong can take control of the cannon to shoot the next three Tusk cannons, which are located on a few stair-like platforms farther ahead. A rope is located behind the cannons, and it can help the ape swing to a wall. The ape is able to wall jump up the wall with the wall to the right of it to reach a higher platform, where a Helper Monkey can be found. This monkey throws him upwards past a cannon and onto an even higher platform.

Here, another Tusk cannon can be found, as well as two walls that the ape can climb. At the top of the walls to the right is a black Hawg, who shoots out flames. Once the foe is defeated, the Kong can advance to a tightrope. He can slide down this tilted rope, while jumping over a few platforms that are occupied by blue Ninjapes, to make his way into a room with some bananas. As he goes to grab these items, the wall behind him closes. If Donkey Kong is to fall while sliding down the tightrope, he lands in a low area full of more Ninjapes. A few gaps are in this area, and they are filled with some spikes. Once the ape manages to find the meeting point of the two pathways, he can follow a green Ninjape to a group of small, yellow fairies. The fairies, when hit by a sound wave, form an orange trampoline, which the ape can bounce on to progress. The trampoline sends him outside of the room, where a trapdoor closes under him. A giant spider enemy is located above the ape at this point. While fighting this enemy, several blue Ninjapes throw their weapons him, however, they disappear when the spider is bested. Once this happens, a giant durian appears on a nearby tree branch. After optionally grabbing the three Banana Bunches lined up against the wall to the left, the Kong can head over to the fruit and bite into it to end the level.

''Super Smash Bros. Brawl
Battle for Storm Hill is referenced in Super Smash Bros. Brawl: its background music plays in the stage, Rumble Falls.

Aerie Fortress
Aerie Fortress is the second and final area of the Durian Kingdom. Donkey Kong utilizes his rope swinging and swimming abilities to make it through the heavily fortified fortress. Similar to the Battle for Storm Hill, Ninjapes use a variety of attacks to keep Donkey Kong at bay. This level also features the Jungle Buddy, Helibird, who helps Donkey Kong ascend through the fortress. After biting into the giant durian at the end of this level, the ape heads out to fight Ninja Kong.

Level Layout
This level begins with Donkey Kong standing on a platform near a rope. The ape can slide down this rope to reach the deepest part of the area. As he slides down, he comes to some groups of three bananas and some wasp enemies. A few additional ropes also appear as the ape slides down. At the end of the ropes, there is a large pool of water. In the water, Donkey Kong comes up to some puffer-fish enemies. Above the second fish is a short pathway leading to a few Banana Bunches. To the right of it is the main path, which is cluttered with big jellyfish enemies. After going through the twists and turns of the area, a current begins to push the ape backwards, however, he can swim through it to access a bigger area. At the end of this room is a giant fish enemy. If Donkey Kong manages to stun it, he can grab into its back fin and ride it through some walls. The fish eventually jumps onto a platform above the water, leaving the ape off before it explodes. A Helper Monkey is near here, and it can throw the Kong to a nearby rope.

More ropes are ahead of this one rope, and they lead to the second Helper Monkey. This monkey throws the ape upwards to a bouncy tightrope, which can be jumped off of to reach another Helper Monkey. Fly enemies are near this Helper Monkey to attack the ape, and another rope is above them. Like the rope before, the ape can bounce off of this to jump higher than usual. A group of small yellow fairies is above this rope, and they form a trampoline when hit by a sound wave, so the rope can boost Donkey Kong to the mechanism. The trampoline can bounce him into a bigger room with a Helibird. If the ape manages to reach the Helibird in this room, who is located in a high-up nest, he can make his way past a small Roc enemy into a tight passage. While heading through the passage, a blue Ninjape throws its weapons at the Kong to attack. Three more of these ninja enemies appear after the ape flies his Helibird through a U shaped passage.

If the ape continues through here, he can enter a large room full of bananas. The small passage continues from here, however, and takes the ape to some Helper Monkeys. In the area located previously after the trampoline, Donkey Kong is also able to miss his Helibird. If this happens, he must continue on foot through the rest of the room. In this area, a small Roc enemy and several Ninjapes appear. Some stair platforms lead the ape out of this room to a wide hallway. Many blue Ninjapes line the ceiling here, throwing their weapons at the Kong. The hallway leads into another room, and in it many black Ninjapes jump out to attack. Some Tusk cannons are also hidden on a small, high platform, and some stairs at the end of the room lead into another hallway. The hallway is occupied by some more blue Ninjapes, as well as a lone Tusk cannon. A large room is near here and a Banande Lion waits at its entrance. The common plant can fling the Kong to a small platform with a fire-spitting Hawg on it.

A Helper Monkey is near this foe, and it can throw Donkey Kong to another platform with a Hawg on it. Another Helper Monkey is near here to throw the ape to a third Hawg and the next Helper Monkey. The monkey here can throw the ape to some more helpers, who can then throw the Kong into a higher area, unless he still has his Helibird to fly him up. In this higher area, there are some insect enemies that attack the ape. A large, moving object surrounds this room, and a few gaps are in it. Once the gap in the mechanism moves over the room's exit, the ape can exit the area to find a room with a Helibird in it. The bird can fly the Kong upwards, where there are some Roc and Tusk foes. Above these two enemies are a few wooden platforms, some of which are covered in flames. If the ape heads higher than these platforms, he can find some more Roc enemies and another Helibird to help him out. The walls around this area are covered in flames, but if the ape manages to fly his Helibird between the gap in the top of the room, he can find a new room with a giant durian. There are two sets of six Banana Bunches on the two ends of the area as well. A Helibird also waits to the left end of the room to fly the Kong to the giant durian. Once he bites into the fruit, the level ends.

VS. Ninja Kong
Donkey Kong must then fight Ninja Kong. Ninja Kong is bulky, with his hair held back. The battle takes place on a large pillar of stone, with a storm going on in the background. During the battle, Ninja Kong will attack by punching, and, if you attack back, he will kick, leaving him open for an attack. If halfway defeated, the process is repeated, but with Ninja Kong continuously kicking until he is open. After being defeated, Ninja Kong will fall over, into unconsciousness.
