Bonus room

A bonus room  (also known as a Bonus Area,   Bonus Level,  bonus stage,   or Bonus Game  ) is a hidden area in the Donkey Kong games, particularly the Donkey Kong Country and Donkey Kong Land'' games.

Bonus rooms are usually revealed either by finding a secret passage or by jumping into a Bonus Barrel. They usually have a challenge that the Kongs must complete to earn a prize needed for 100% completion. In Donkey Kong Country games developed by Rare, after the player has uncovered all the bonus rooms of a given level, an exclamation point is added after its title; in the Donkey Kong Land series, an exclamation point is still marked but is not appended to the end of the level title.

Donkey Kong Country


Bonus Levels first appear in Donkey Kong Country. Here, they are entered by either breaking open certain walls with barrels or Animal Friends to reveal secret passages, or by jumping into certain Blast Barrels (changed to Bonus Barrels in the Game Boy Advance remake). In Oil Drum Alley, there is a Bonus Level entrance hidden within another Bonus Level, which can be entered by using a barrel to smash open its entrance. These rooms can only be entered once (except in the Game Boy Advance remake).

Bonus Levels appear in every level except for the underwater stages and Mine Cart Carnage. There are usually two or three Bonus Levels in a level, although five of them appear in Orang-utan Gang, which has the most Bonus Levels out of every level.

Unlike in subsequent appearances, the main idea of Bonus Levels is to obtain common items, such as bananas, animal tokens, or even a Life Balloon. The Kongs do not have to complete a challenge or collect the items within to add to their completion percentage—this occurs by simply entering the Bonus Level itself. There are 67 Bonus Levels in the game.

In the Game Boy Color remake, Candy Kong hosts a challenge in each world. The challenges are very similar to Bonus Levels, except for an award at the end (a Banana Bunch Coin); the challenges even have the same theme as a Bonus Level.

There are several types of Bonus Levels. In the Game Boy Advance version, each type received its own distinct title and splash screen:

*Levels with a (B) are accessed via a Bonus Barrel. Levels with a number (e.g. 2) tells how many of that type is in the level. There is also a specific type of Bonus Level that features an Animal Friend, either Rambi, Expresso, Winky, or Enguarde. Each Animal Friend's stage has a unique theme and layout, and some are based on their most common environment. Additionally, just like regular Bonus Levels, each of the Animal Buddy ones also received their own splash screen and title in the Game Boy Advance remake. The Bonus Levels revolving around Animal Friends do not reappear in any of the subsequent Donkey Kong Country or Donkey Kong Land titles.

An Animal Friend's Bonus Level can be accessed by collecting three animal tokens of the same Animal Friend. Upon collecting the third token, the Kongs are warped into a Bonus Level, where they play as the corresponding Animal Friend. The goal of these Bonus Levels is for the Animal Friend to collect as many Mini Animal Tokens within the time limit. A Big Animal Token is also hiding in the location, which doubles the Kongs' Mini Animal Token total. When the time runs out, the Mini Animal Tokens are subtracted, and the Kongs receive an extra life for every 100 Mini Animal Tokens they have collected (similar to bananas). Additionally, in the Game Boy Advamce version, if an Animal Friend manages to obtain 600 Mini Animal Tokens (400 for Enguarde), a photograph of that Animal Friend is added into the Scrapbook.

Donkey Kong Land
Bonus Levels reappear in Donkey Kong Land. Just like with Donkey Kong Country, the Bonus Level variations do not have a name, and every Bonus Level must at least be accessed to add to the 100% completion score. While many of the Bonus Levels are accessed via the same methods, some are accessed via a new method: by falling on a ground patch from a height, causing a vertical rope to fly out. By grabbing on the rope, the Kong is dragged up into a Bonus Level.

A new type of Bonus Level is introduced in the game. In it, the Kongs' collected Kong Tokens are shot out of a revolving Barrel Cannon. The cannon fires out one Kong Token a time, if DK or Diddy jump on a ground switch. By collecting a Kong Token, the Kongs win an extra life. The only other type, which is also the most common one, involves the active Kong trying to reach the end goal, much like "Find the Exit!" from Donkey Kong Country.

Donkey Kong Country 2: Diddy's Kong Quest / Donkey Kong Land 2
In Donkey Kong Country 2: Diddy's Kong Quest, Bonus Levels are entered much like in its predecessors, except that the Blast Barrels leading to a Bonus Level were replaced with Bonus Barrels. Every level has between one to three Bonus Levels. The types of Bonus Levels were narrowed down to three, none of which reappeared from Donkey Kong Country. Each type is a time-based challenge that the Kongs must complete to be rewarded with a Kremkoin. In the Lost World, every level only has a single Bonus Level, with a Hero Coin as a reward (given that Kremkoins' purpose is to unlock a level of the Lost World). Unlike in the first game, Bonus Levels can now be reentered. Bonus Levels were also featured in Donkey Kong Land 2 where their role is unchanged, and the same three types were retained.

Uniquely in Donkey Kong Land 2, no Collect the Stars! bonus stages used in the game have any enemies, and no Destroy Them All! bonus stages have any bananas. This is because the star counter for Collect the Stars bonus stages is shared with the enemy counter for Destroy Them All bonus stages, and collecting stars/bananas and defeating enemies all affect the counter, regardless of which type of stage is played.

The Bonus Level types first received their own title card each in Donkey Kong Country 2, and the title cards were retained for Donkey Kong Land 2:

Donkey Kong Country 3: Dixie Kong's Double Trouble! / Donkey Kong Land III
In Donkey Kong Country 3: Dixie Kong's Double Trouble!, Bonus Levels have a similar role as in Donkey Kong Country 2, except that all of them are accessed by entering a Bonus Barrel and none from breaking open a wall. The reward for completing a Bonus Level was changed from a Kremkoin to a Bonus Coin. There is always a consistent number of two Bonus Levels per level, except for Krematoa, where the number of Bonus Levels varies from zero to three. Rocket Rush is the only level without any Bonus Levels. All the Bonus Levels from the previous game returned (although with different titles), and a fourth, new type was introduced, "Grab 15 Bananas!". "Collect the Stars!" was renamed to feature the number of stars in the title, for example, "Collect 50 Stars".

In Donkey Kong Land III, the Bonus Levels have a similar role as in Donkey Kong Country 3, except that Grab 15 Bananas! is not featured. Therefore, every Bonus Level type is the same as in Donkey Kong Country 2 and Donkey Kong Land 2, even going as far to retain the original names (except for "Bash the Baddies!"). An extra exclamation mark was added in each Bonus Level's title, except "Collect the Stars!". In addition, unlike in Donkey Kong Land 2, some Collect the Stars! bonus stages have enemies, and some Bash the Baddies! bonus stages have bananas. (While the enemy counter is still shared with the star counter, like in Donkey Kong Land 2, the counter is only affected by enemies in a Bash the Baddies! stage, and is only affected by stars/bananas outside of a Bash the Baddies! stage).

Donkey Kong 64
Bonus Levels return in Donkey Kong 64, where they were renamed "bonus stages." Most bonus stages are accessible by jumping in a Bonus Barrel. Only the Minecart Race is the one that can be entered by entering a specific area. After the player has cleared a stage, the player is rewarded with a Golden Banana. Most of the stages can be played in Snide's H.Q. after collecting all Blueprints. The following is the list of all bonus stages in Donkey Kong 64: Enguarde and Rambi each have an unlockable mini-game (somewhat in the style of a bonus stage) that can be played from the main menu. The minigames are respectively titled Enguarde Arena and Rambi Arena. Both games can be unlocked after capturing six Banana Fairies in the main game. These bonus stages are somewhat similar to the ones from Donkey Kong Country that feature an Animal Friend, as an Animal Friend are also the main feature of both mini-games.
 * Batty Barrel Bandit: Stop the four reels of the slot machine on four bananas to earn a point. The player must do this a required number of times to win.
 * Beaver Bother: The player controls a Klaptrap and tries to chase the Gnawties into the hole in the center of the barrel. Klaptrap must be careful not to fall into the hole itself, else it automatically loses at the mini-game.
 * Big Bug Bash: The player must use a fly swatter to swat a given number of flies within the time limit.
 * Busy Barrel Barrage: Standing the middle of a big barrel, the Kong must fire ammo at incoming Kremlings. The Kong loses if hit by an enemy.
 * Krazy Kong Klamor: Lights repeatedly flicker on and off. When they turn on, the player must shoot at Golden Banana while avoiding the Kongs.
 * Kremling Kosh: The player uses a watermelon-firing cannon to shoot at Kritters who pop out out from the barrels. Normal, green Kremlings are worth one point, while red ones are worth two points. The player's objective is to shoot the required number before time runs out.
 * Mad Maze Maul: The active Kong must defeat every enemy in a maze and then cross the finish line.
 * Mine Cart Ride: In a mine cart, try to collect the required number of coins before the exit.
 * Minecart Mayhem: The active Kong rides around in a Mine Cart and must avoid being hit by moving TNT Barrels by switching lanes until time runs out.
 * Peril Path Panic: The objective is to fire watermelons at the Klaptraps to temporarily subdue them, allowing the Banana Fairies to safely cross the path.
 * Searchlight Seek: Using a spotlight, the player locate the Klaptraps and then fire at it.
 * Speedy Swing Sortie: The active Kong must climb up a tree and swing from vines to collect the coins.
 * Splish Splash Salvage: The active Kong must swim all the way down a large barrel and collect all the coins below.
 * Stash Snatch: While going around a maze, the player must collect all the coins while avoiding Kremlings and then cross the finish line.
 * Stealthy Snoop: The player must go through a maze and find the finish line while avoiding the Kops, who shine their flashlight onto the Kong.
 * Teetering Turtle Trouble: Turtles are spinning around on the snakes' tails. To keep them spinning, the player must shoot a melon into a snake's mouth.

Donkey Kong Country Returns / 3D
Bonus stages return in Donkey Kong Country Returns and Donkey Kong Country Returns 3D, once again accessed by Blast Barrels (as Bonus Barrels do not return in this game) and secret passages, although now with only one objective. The Kongs have thirty seconds to get all bananas, Banana Bunches, Banana Coins, and Red Balloons available. If they successfully collect all of them, the clock stops and a Puzzle Piece appears for them to collect.

Like in the past Donkey Kong Country games, the setting of a bonus stage depends on the world it can be found in, and it is always set in a cavernous or dimly lit room. Despite the aesthetic changes, bonus stages repeat themselves throughout the course of the game, meaning they are not unique to their levels, unlike in previous games.

Donkey Kong Country: Tropical Freeze
Bonus stages appear in Donkey Kong Country: Tropical Freeze, having been renamed "bonus rooms" in the American English version. The objective of bonus rooms remains almost the same as in the previous game – the player has to collect all 100 bananas on-screen within thirty seconds, receiving an additional Banana Coin and a Red Balloon along with the Puzzle Piece. However, the setting of a bonus room is not related to the world it appears in anymore. Instead, all bonus rooms take place in what appears to be a treasury, with some of them being adorned with large statues in the background, suggesting they are connected to or branched off Secret Seclusion. As in the previous game, bonus rooms repeat themselves.
