Toxic Tower (Donkey Kong Country 2: Diddy's Kong Quest)

Toxic Tower is the thirty-third level of Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2. It is the sixth area of K. Rool's Keep.

This castle level is the final test before Diddy Kong and Dixie Kong finally reach the top of K. Rool's Keep. Throughout the level, poisonous slime rises up through the dungeon, and it can damage the Kongs easily if they are not fast enough at climbing. Luckily, they are not alone, as Rattly the Rattlesnake, Squawks the Parrot, and Squitter the Spider can be found in three areas of the level to help them make their way up the stage. Each one is vital to beat the level, as the level has obstacles that only a certain Animal Buddy can cross. Even with the slime rushing up, Klampons, Kaboings, Kannons and Zingers wait all around the the tower to end the Kongs' adventure for good.

''Donkey Kong Country 2
From the start of the level, the Kongs must climb up a few ledges while defeating a few Klampons. Soon, they will enter an Animal Barrel, and turn into Rattly the Rattlesnake. The slime will begin to rise here, so Rattly must quickly hop up all the platforms to the left of him, and also beat the Kaboings in his way. After jumping to all the platforms here, the snake will have to hop up to the next floor and bounce off of a few Zingers to cross a wide abyss. He must bounce off of another Zinger after that and leap up several platforms scattered around the area. Once at the top of the platform in the top-right corner, Rattly will need to bounce off some more Zingers, then jump up to some thin platforms and hop across them. Again, he'll have to jump to a higher floor and bounce over a few thin platforms. Here, he should bounce off of a Kannon to make it to the next floor. At this point, the Animal Buddy will have to super jump to the area above him and hop off of more Zingers to cross another abyss. When on the other side, Rattly must jump up a few short floors while watching out for Zingers, and then bounce off of more Zingers in another area to reach a high platform. Once up here, the snake should jump up into the air and land right into another Animal Barrel. It will turn him into Squawks, who must fly upwards and break the Star Barrel.

At this point of the level, Squawks must continue up the path and defeat all the Zingers in his way. He will also have to beat some Kaboings on his journey upwards, and still even avoid the rising slime. Near the end of Squawks's part of the level, he will have to defeat many Zingers in his way to get through small openings. He'll then have to continue upwards and dodge a few more Zingers, until he finally makes it to the third Animal Barrel. It will turn him into Squitter the Spider, who must build his web platforms and get up to the top-left corner of the area. Here, Squitter will have to enter a barrel and be shot strait up to the No Animal Sign. This will turn him back into the Kongs, who must travel a little farther to find the End of Level Target. It will take them out of the level.

''Donkey Kong Land 2
At the beginning of the level, the heroes will need to climb across some chains and climb upwards on another one shortly after. The slime will start rising here, so they must act fast. Quickly, the Kongs will have to hop into the Animal Barrel, turning them into Squitter. Squitter must then create web platforms to make it up to the top-right corner of the area. He must continue up, dodging the slime, until he makes it to the first No Animal Sign. It will turn him back into the Kongs, who must jump up a few ledges to get in another Animal Barrel. It will turn them into Rattly the Rattlesnake. Rattly will need to bounce up a few more ledges and cross a few gaps while hopping eastward. Soon, on the next floor, he'll meet up will the level's first Zinger and have to bounce off of him, along with a second wasp, to reach a higher ledge. From there, the Animal Buddy must use his special ability to jump extra high and get to the next floor. Here, he will have to bounce over more abysses going east and then jump to the floor above. In this floor, there are many platforms. Rattly has to jump up to the top platforms and climb up to the top-left corner of the area. at this point, the snake will need to climb up some ledges and enter another platform-filled area. Using the banana trails, forming arrows, he must super jump his way up this floor, until he gets to another No Animal Sign. It will turn him back into the monkeys, who need to climb up a chain to access the next floor, and find the Star Barrel.

At this point, the heroes must climb up some more chains and watch out for Klingers sliding down them. Once they make it to the next area, they have to defeat a few Kaboings and enter an Animal Barrel. It will turn them into Squawks. The bird must make his way through the path and follow the banana trails for extra help. As he goes, he'll also have to defeat several Zingers lurking around the area. Soon, the Animal Buddy will have to avoid two Krooks throwing their hooks at them, and make his way up to a fork-in-the-road. He can go either east or west, although both sides follow the same obstacles. Once he chooses a direction and makes it back to the single-road, he must continue upwards and beat all the enemies in his path. As the bird progresses, more and more Zingers will stand in his way, and the level will become a bit trickier. Eventually, however, Squawks should encounter the final No Animal Sign of the level, and pass it to transform back into the Kongs. After that, the monkeys must climb up to the top floor using several chains. There are Klingers on these chains, so they need to be careful. Once at the highest point, the heroes should travel west and find a spring. They can use it to exit the level.

Bonus Level

 * Near the end of the level, Squitter must build his web platforms up to the first Zinger he sees against the wall to the right. He has to defeat this foe, and then go through the wall behind it. If he does so, he is able to make his way to the nearby Bonus Barrel, leading to the Bonus Level. Here, the spider must build more web platforms to climb to the top of the Bonus Stage. There are brambles all around him, so he must be careful when he jumps. If he gets to the top of the area within 30 seconds, he is awarded with a Kremkoin to grab with the remaining time.

DK Coin

 * After Rattly finds some bananas in the formation of the letter A, he must jump up and get over several thin platforms. After the last platform, he can find a Zinger between two structures. The snake must defeat this foe and fall down the small gap below it to make his way into a small alcove, where the DK Coin is located.

Golden Feather (Game Boy Advance version only)

 * To get the Golden Feather, Rattly must enter an area filled with platforms, where he can find the letter K. Then, he should bounce down to the platform below it and preform a super jump. He is able to grab the feather in mid-air when doing this.

Photograph (Game Boy Advance version only)

 * After the Kongs turn into Squitter, they have to build webs past the level's Bonus Stage to find a Zinger with a photograph over its head. If the spider defeats this enemy, he is given a photograph to help add a picture to the Kongs' scrapbook, exclusively in the Game Boy Advance remake of Donkey Kong Country 2.

Bonus Level

 * Near the beginning of the level, Rattly meets the level's second enemy: a Zinger. Instead of jumping on this foe to reach the next ledge, the snake should simply hop right past it to enter the Bonus Barrel. Once he is in the Bonus Level, he has to bounce off of many insects to make his way across a wide gap. If he reaches the other side within the time limit of 10 seconds, he can grab the Kremkoin and exit the bonus with the remaining time.

DK Coin

 * At short while after the first Bonus Barrel, Rattly accesses a large area filled with many platforms. On the first level of platforms, he must bounce his way to the left. He should see the DK Coin in a small alcove around this area.
