Mudhole Marsh (Donkey Kong Country 2: Diddy's Kong Quest)

Mudhole Marsh is the twenty-first level of Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2, a similar game for the Game Boy system. It is also the fifth area of Krazy Kremland, and the sixth area of the same world in Donkey Kong Land 2.

Outside of the park, the Kongs find themselves in another swamp. This swamp is the most treacherous one there is, as the Kongs have to rely on Krocheads, platforms, and even Barrels shot by Kannons to cross the dangerous waters. Exclusively in Donkey Kong Country 2, the Kongs meet the foe, Cat-O-9-Tails in this level. Other enemies include Zingers, Flitters, Click-Clacks, Kannons, and Mini Neckies, who are scattered throughout the whole level. Klingers and Klomps also appear exclusively in Donkey Kong Land 2.

From the start of the level, the Kongs must avoid a few Flitters and cross the water area, using the platforms in it. After that, they must go east, as they did before, and watch out for a Cat-0-9-Tails, who can throw them to their death. There is another abyss after this, and the heroes must use the hooks above it to get across. They will reach land then, and have to dodge two Click-Clacks. From that point, they need to cross another abyss, and, once, again, platforms are needed to do so. As they cross it, Mini Neckys will swoop down and attack them, and the monkeys must avoid them at all costs. After this, they should make it to a large platform, with another Cat-0-9-Tails. Once they defeat that foe, they will get to another abyss, and hooks are needed to cross it. As they hop to each hook, Zingers will lurk nearby, and can be quite a hazard. Soon, the Kongs will bounce off a Flitter and onto more small platforms. Again, Mini Neckys will be encountered, and they will attack as soon as the group is close enough. The heroes must not only use platforms at this part of the level, but also bounce off of several Flitters to cross wider gaps between the platforms. After these obstacles, though, they will reach land again, and then cross another abyss, where the Star Barrel can be found.

As the monkeys jump to these platforms, they'll meet another Mini Necky, but soon get back on solid ground. Continuing east, they will have to dodge a Cat-0-9-Tails and grab onto a vine in the water. They need to keep going across the dangerous waters and hop platform-to-platform. They'll also encounter a Kannon on the way. After that, the Kongs must leap off a red Krochead, and then get back on land. Zingers and Cat-0-9-Tails are placed throughout the area, so the heroes should be careful. Eventually, they will have to go over another abyss, and again, use the platforms. A Kannon will shoot Kannonballs at them when they begin to cross, but they can be avoided with a simple jump. Back on land, the monkeys will have to defeat three Click-Clacks, and shortly after, cross yet another abyss. To cross it, the group must use platforms, Flitters, Krocheads, and even barrels shot from Kannons. Once they make their way back on land, they will reach a large platform. They'll soon have to jump off though, and get over the next abyss. This one is very small, and only a single Krochead is needed to cross it. After this point, the Kongs will get back to solid ground and walk eastward. As before, there are Cat-0-9-Tails and Zingers all around to mess with the monkeys, so they need to be very cautious. Finally, the heroes will have to cross the last abyss in the level. Unlike other ones, however, this abyss has little platforms. Instead, the group must use the barrels from a nearby Kannon to bounce across the whole length of the gap. Eventually, though, they will get to land again, and walk along the area, where they will find the Ending Pad.

When starting the level, the Kongs should travel east and cross the abyss, using platforms and a vine. After that, they will be back on land, and then get back over another abyss. When they cross it, they may use either the hooks hanging in the air, or the platforms in the water. They can use both, too. Once over this abyss, the Kongs will walk up to a third one. As they get on each platform, there will be Mini Neckys swooping down at them. Once they are all avoided, the heroes will bounce off of a few Flitters and get to a vine with a Klinger on it. They must dodge this foe, and finally get back on solid ground. But, right after that, they will go over another abyss. As they jump platform-to-platform, more Mini Neckys will attempt to attack them, and they can be dangerous. Eventually, the monkeys will get back to land, where they will find the Star Barrel.

Halfway through the bayou, they must cross yet another abyss. They'll have to jump to a few vines, which have Klingers on them, and then, as usual, dodge several Mini Neckys. After bouncing off a couple Flitters, they will get back on land. They must jump on some Klobbers here, and cross the next abyss, where there is a Krochead Barrel. When hit, Krocheads will emerge from the water, and can be used as stepping stones. After this abyss is crossed, the monkeys will get back on land, and soon have to go over the following abyss. They need to hit another Krochead Barrel here, and then hop on a couple of Krocheads. From this point, the group will, again, cross an abyss. Krocheads and half-sunken barrels can help them get across. As usual, there is another abyss after this one. It's fairly short, but is followed by yet another abyss, where there are more Mini Neckys swooping down to attack. After this point, the heroes must bounce off of several Flitters and hit a Krochead Barrel. When the Krocheads stick their heads out of the water, the monkeys need to jump on them to cross. Finally, the Kongs will get back to solid ground, where they will see a spring, which can take them out of the level.

Bonus Level(s)

 * Before the Star Barrel, the heroes should see a Bonus Barrel floating in plain sight above a Cat-0-9-Tails. Using a Team Up move, they can reach it and enter the Bonus Level. Here, they have to jump over each platform and collect all the stars they see. When they are all obtained, the Kremkoin appears nearby.
 * Near the end of the level, the Kongs can see a Kannonball. They should pick it up and head across the platforms they are on. Soon, they can notice a cannon on the very last platform over the abyss. After they load up this cannon with the ball, they must simply walk into it and begin the Bonus Level, where they need to use more kannonballs to hit all of the enemies they see. Once the two Flitters and the three Zingers are defeated, the Kremkoin appears nearby.

DK Coin

 * The DK Coin is one of the prizes the Kongs get if they hit the End of Level Target well. With correct timing, they need to use the barrels shot from a nearby Kannon to bounce high enough and hit the top of the target. They can win the coin if they hit it at the right time.

Golden Feather (Game Boy Advance version only)

 * The Golden Feather is right in front of the second-to-last Kannon that the Kongs encounter. To collect the item, they must first defeat the foe. Then, they must perform a cartwheel towards the feather and jump back on land once it is grabbed.

Photograph (Game Boy Advance version only)

 * Shortly after finding the letter N, the heroes meet a group of Mini Neckies, who swoop down at them. The foe above the other members of the group has a photograph over its head. When this Mini Necky swoops down at the Kongs, they need to fight back and jump on him, defeating the small creature. They are then given the special photograph to add to their scrapbook.

Bonus Level(s)

 * At some point in the level, the Kongs can see bananas in the form of an arrow pointing up. They should bounce off of the Mini Neckys next to them and then land into the Bonus Barrel above. In its Bonus Level, they need to hop to several ropes, collecting a few stars on the way. When all of these stars are collected, the Kremkoin appears nearby.
 * A little while after that first Krochead Barrel, the primates find a kannonball. They need to pick it up and carry it across two short abysses. After that, they can spot a cannon on a large platform. They must load it up by throwing the ball into it. If they walk into it, the cannon blasts them into the Bonus Level. Here, the group has to climb vines and jump off Flitters to the end of the stage, where the Kremkoin is present.

DK Coin

 * To get the DK Coin, the heroes must complete the second Bonus Level. When they leave the stage, they are shot right to the coin.
