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.

The level begins on a grassy bridge that is held over the swamp water. Three Flitters attack the heroes as they walk across this area, but they can use the enemies to their advantage by jumping on them to reach a Banana Coin. A water area is ahead that they must cross by using half-sunken barrels and lily pads. A hook floats in the air above the objects. As the Kongs approach land again, Flitters attack them and they meet the first Cat-O-9-Tails in the game. It can throw them to the letter K or harm them. Another gap full of water is ahead that must be crossed with the hooks floating above it. Click-Clacks walk along a small platform ahead of here. There is another water section after this platform that can be crossed if the Kongs jump along the lily pads and half-sunken barrels in it. Mini Neckies attack them as they cross, diving at them. A treasure chest containing a Banana Bunch is on the first lily pad as well.

Once the Kongs cross the water area, they reach another small platform supported over the swamp. It has a Cat-O-9-Tails on it. Using more hooks, the primates can cross most of a long section of water after here. Zingers surround some of the hooks. A Flitter is also after one of the hooks that must be bounced on to avoid landing in the liquid. Lily pads and barrels must be jumped on throughout the remaining part of the water area once the heroes bounce on this Flitter. As the primates travel down the swamp with the lily pads and barrels, Mini Neckies swoop down at them. They come up to a DK Barrel and many treasure chests on the way as well. As the heroes approach the end of the water section, they encounter a few Flitters, whom they must bounce on to cross small gaps between lily pads. Once they Kongs cross this water area, they reach another bridge platform supported over the liquid. It has a Cat-O-9-Tails on it. There is another water area just ahead of here, which the heroes begin crossing by bouncing on a Flitter to reach a lily pad. They must continue along the lily pads and the barrels in the water to progress safely. The Star Barrel floats above the first half-sunken barrel in the water.

A single lily pad is located after the special barrel. It is followed by another solid bridge platform. A Cat-O-9-Tails rests here. A pair of Zingers also fly in the air above the platform, guarding a group of bananas. If the Kongs travel forward, they can find another water area with more lily pads and barrels that they need to cross. Vines must also be used in this area to progress. A Kannon is on the first barrel, and the letter N is right in front of it. Three vines follow the foe, allowing the primates to reach a Krochead that can fling them over a Zinger and onto a platform held above the water. Here, there are two Cat-O-9-Tails, along with a second Zinger, who guards bananas and a Banana Coin. A third Zinger is at the end of the platform at the beginning of another water area. Here, the Kongs must hop along lily pads and barrels to progress. A Kannon shoots at them as they hop along the objects. They pass a DK Barrel and a kannonball on the way across as well. A barrel holding a cannon that leads to a Bonus Level is after the Kannon. Another platform is also immediately after it. Three Click-Clacks march along it. An additional area of water is ahead. After the heroes bounce on a Flitter here to cross a rather large gap, they reach a vine that they can cling onto. Using more vines, lily pads, barrels, and even a Krochead, they must hop over the gaps in the water area.

After they pass the second Flitter, they reach a large gap that they can cross by bouncing on a barrel shot from a Kannon nearby. A few Flitters are ahead of here that can aid the Kongs in crossing the area. A bridge platform that supports a treasure chest, containing a Banana Bunch, is right after the Kannon enemy. A small gap of water is after it, but only a green Krochead must be hopped on to cross it. On the other side of the water area, the primates can spot two Cat-O-9-Tails and a few Zingers who fly near the letter G. There is another water area following this. Once they hop along the first lily pad and the first barrel, they find a large gap ahead of them. A Kannon is on the other side of the gap shooting barrels, so the heroes must bounce on its projectiles to cross. A Flitter flies over a gap immediately after the Kannon that the Kongs can bounce on to reach a solid platform with another Kannon on it. An End of Level Target is at the end of this platform. They must jump on it to complete the level. They can win a prize from the target mechanism if they jump on it from one of the barrels shot from the nearby Kannon.

''Donkey Kong Land 2
The level starts out on a platform supported over the water. Many Flitters fly towards the primates as they move along the short platform. An area of water follows this platform. By using a half-sunken barrel, a lily pad, and a vine, the Kongs can cross it and reach a longer bridge platform with a DK Barrel on it. Another section of water is after this platform, and it must be crossed by using lily pads and barrels as platforms. Hooks found above these objects can also be used to cross. The letter K can be found in a lower part of the area. Once the second water area is crossed, the heroes make their way onto another bridge platform, which is raised over the liquid. Two Click-Clacks and a treasure chest containing a Banana Coin stand on it. The third area of water is near here. As the primates use a barrel and a lily pad to begin crossing, Mini Neckies attack them.

After the first mob of Mini Neckies, they find a Flitter flying ahead that they must bounce on to reach a lily pad placed nearby. After the heroes travel along more lily pads in this area, they reach a large gap between a lily pad and and a barrel platform. They must bounce on two Flitters located between the gap to cross it. Once the gap is crossed, the Kongs can find a vine near them with a Klinger sliding on it. A bridge platform raised above the water is ahead of the vine. It has a DK Barrel and a Klobber on it. There is another section of water following this platform. As they cross this by jumping along many small lily pads and bouncing off of Flitters, groups of Mini Neckies attack them. Near the end of this water area, the heroes can find a few Flitters floating in the air. They can bounce on them to reach the letter O. A platform raised over the water is below the letter. The Star Barrel waits on it.

There is another area of water immediately after the Star Barrel. They must cross the beginning of it by clinging onto several vines, most of which have Klingers on them. As they approach the end of the swamp area, they find more lily pad and barrel platforms to cross with. As they travel through this area, Mini Neckies dive at them. A Zinger also stands in their way. Just before reaching solid ground again, the primates encounter a large gap with Flitters above it. They can cross it by bouncing on the enemies. Once they get over the water, they land on a long platform suspended over the liquid. Two Klobbers and a DK Barrel are on it. A Mini Necky is also at the end of it. There is an area of water after this foe that must be crossed by jumping along half-sunken barrels, lily pads, and Krocheads, who only appear when a Krochead Barrel is hit. A Flitter can also help them as they travel forward. Near the end of the water area, a Zinger stands in their way. If they manage to make their way ahead of it, they can make it onto a raised bridge platform with a kannonball on it. There is a second Krochead Barrel near here that can summon two Krocheads to appear in a water area just ahead.

Another raised platform is on the other side of this gap with a Flitter around it. There is another water area ahead. Using Krocheads, lily pads, and half-sunken barrels, the heroes must make their way across the liquid and onto another solid platform suspended over the water which has a cannon leading to a Bonus Level on it. A Zinger impends in their progress as they travel. If the primates travel farther into the level, the come up to the next section of water, which they can cross by bouncing on a single Flitter and by hopping along a barrel. Another raised platform is after here with a Klomp on it. A water area is also ahead of here, which must be crossed by using lily pads and half-sunken barrels as platforms. Mini Neckies attack the heroes as the travel here. Farther into the area, they encounter many Flitters, whom they must bounce on to cross a gap. Upon landing on a barrel platform after the last Flitter here, they hit into a Krochead Barrel that makes several Krocheads appear ahead. Flitters are between some of the crocodiles to help the Kongs cross gaps between them. Once this area is crossed, they make their way onto a raised platform with a spring on it. The letter G is located right after it. The level is completed when they bounce on the spring.

K-O-N-G Letters

 * K: The letter K is in the air above the first Cat-O-9-Tails, who can throw them to the letter. They can also reach it with the Team-up move.
 * O: The letter O is in the third treasure chest in the level. It can be opened if they throw it at an enemy.
 * N: The letter N is in front of the first Kannon. The heroes must bounce on a barrel the foe shoots to grab the letter and bounce to safety.
 * G: The letter G is next to two Zingers near the end of the level. It can be found on the platform just before the second-to-last Kannon in the level. The Team-up move must be used to reach it.

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.

K-O-N-G Letters

 * K: The letter K is in the lower part of the second section of water. A Flitter is placed next to it for the Kongs to bounce on so they can avoid falling.
 * O: Just before the Star Barrel, the Kongs bounce along many Flitters to cross an area of water. After they bounce on the last Flitter, they reach the letter O, found above a trail of bananas leading onto the platform with the Star Barrel.
 * N: The letter N is right after the first Krochead Barrel.
 * G: The letter G is located after the spring at the end of the level.

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.
