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 the Kongs finally reach the top of K. Rool's Keep, and it's far from easy. Throughout the level, poisonous slime will rise up through the dungeon, and it can damage the Kongs easily if they aren't 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 make their way up the dangerous stage. Each one is vital to beat the level, and have obstacles that only a certain Animal Buddy can cross. Even with the slime rushing up, Klampons, Kaboings, Kannons and Zingers will wait all around the the tower to end the Kongs' adventure for good.

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(s)
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 will have to defeat this foe, and then go through the wall behind it. If he does so, he will be 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 all the way to the top of the Bonus Stage. There are brambles all around him, so he must be careful when he jumps. Once he gets to the top of the area, he will be awarded with a Kremkoin.

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 will see a Zinger. The snake must defeat this foe and fall down the small gap below it. He should make his wall to an alcove on the right of the gap, where the DK Coin is.

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

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

Bonus Level(s)
Near the beginning of the level, Rattly will meet the level's second enemy: a Zinger. Instead of jumping on this foe to reach the next ledge, the snake should just hop right past it an enter the Bonus Barrel. Once he is in the Bonus Level, he will have to bounce off of many insects to make his way across a wide gap. When he reaches the other side, he can grab the Kremkoin and exit the bonus.

DK Coin
