The second game in Rare's Donkey Kong Country trilogy for the Super Nintendo, released in 1995 and later ported to the Game Boy in the form of Donkey Kong Land II and a closer remake for the Game Boy Advance.While relaxing at the beach Donkey Kong is kidnapped by Kaptain K. Rool (an alter ego of the first game's villain, King K. Rool) and held for ransom for the Kongs' banana hoard. Instead, Diddy, accompanied by his girlfriend Dixie, decides to go after K. Rool and rescue DK themselves, starting by invading the Kremlings' ship and venturing through Crocodile Isle to get him back.Diddy's Kong Quest significantly adds to the mechanics introduced in the first game. Bonuses are no longer simply free ways to gain bananas and lives, but challenges in and of themselves, offering kremcoins as rewards, used for another introduced mechanic: A secret world. In addition, this is the game that first introduces "hero coins," giant coins with the word "DK" on them, one of which is found in each level.
Bait-and-Switch Boss: Considering it's name and level theme, K. Rool's Keep leads one to believe its boss will be K. Rool. Instead, the player gets just a cutscene in the SNES version and a different boss for the GBA version, while K. Rool waits in a secret world afterward.
Brutal Bonus Level: The Lost World. Access to a level can be bought for each world at 15 kremcoins each from Klubba's Kiosk. They are much harder than the regular levels, which is saying much. Specific levels of note:
"Animal Antics" because of the infamous area forcing you to fly through tight bramble passages as Squawks while the constantly shifting wind keeping blowing you forward and back.
"Klobber Karnage," which forces you to move over large pits of spikes in barrels, trying to time the tilting of the barrel and when to shoot into another barrel to avoid hitting bees, requiring tight timing.
Chest Monster: In addition to the regular ones that bump you around and the TNT versions that explode on contact, this game also has yellow Klobbers that knock bananas out of you and black Klobbers with red eyes that can even bump lives out of you.
Convection Schmonvection: Crocodile Cauldron, to the extent that some crocodiles can apparently lie in the lava with only their heads above the surface while Diddy and Dixie have no problem hopping on their heads, inches away from the lava. Hell, in Redhot Ride hot air balloons can sink halfway under the lava.
Darker and Edgier: Noticeable from the very beginning. Just compare the map screen of crocodile island, with its darker palettes and foreboding music to the original game's brighter jungle and jauntier music.
Dark Reprise: "Jib Jig" is a stormier version of the "Ship Deck" theme.
Within the game itself, either world 3 or 4 is often viewed as the time the game starts getting difficult. Most notably with Slime Climb in the former and Bramble Scramble in the latter.
Dummied Out: Diddy and Dixie's mourning sprites, as well as death and victory themes made especially for the final bosses.
Elevator Action Sequence: Castle Crush could arguably be an example—except, as the name indicates, the player fights more against the various walls and ceilings trying to squish the player against the rising floor.
Game-Breaking Bug: There's a bug in Castle Crush that crashes the game, and from there can generally end in three ways: option one is nothing important happens, option two is all of your saves getting deleted, and the third option, if luck isn't on your side, can render the game cartridge itself pretty much screwed over beyond repair— thus being a literally game-breaking bug.
The hero coin in Bramble Scramble, which expects you to jump through a fake wall of brambles. Only a stray banana and the subtle movement of the camera tips the player off.
The second bonus in Chain Link Chamber, in the door behind the Kannons. Not only does it seem just like a background element, even if you see it you have to find a certain walk-through wall in order to reach it.
And who would guess that you need to beat all of Swanky's Bonus Bonanza quizzes to get 102%?
The cheat to unlock all 75 Kremcoins is so obtuse it wasn't on Gamefaqs until recently.
Hailfire Peaks: Krem Cauldron, a mix of Crocodile Cauldron and Krem Quay, from Donkey Kong Land 2.
The Hedge of Thorns: The Bramble levels: Bramble Blast, Bramble Scramble, and Screech's Sprint.
Hints Are For Losers: The manual has a section called "Cranky's Hints". There, Cranky just berates you for being so naive and tell you to buy the upcoming Nintendo Power guide instead. It also didn't help that the credits show that the manual was made by Nintendo Power as well.
