Donkey Kong Jr. (game)

Donkey Kong Jr., also spelled Donkey Kong Junior in early arcade releases and home ports, is an arcade game starring Donkey Kong Jr. It is the direct sequel to Donkey Kong, and it and the similar Donkey Kong II, as well as Donkey Kong Circus are the only games in the Mario franchise where Mario is the antagonist. Donkey Kong Jr. never enjoyed the sales or the following that the original Donkey Kong did, but it did well enough to warrant a second sequel, Donkey Kong 3.

Story
After the events of Donkey Kong, Mario has captured Donkey Kong as revenge for kidnapping his lady friend and Donkey Kong Jr. has to save him. Donkey Kong Jr. will travel through four stages from the jungle to the big city to rescue his father, climbing vines, avoiding enemies and jumping on platforms along the way. However, every time Donkey Kong Jr. gets close to freeing his father, Mario just pushes him further away.

Finally in his hideout, Mario appears to be atop a skyscraper similar to 100m from the last game. Donkey Kong Jr. has to put six keys into their keyholes to free his dad and make the platform they are standing on disappear. Donkey Kong and Mario both fall down and Donkey Kong Jr. catches Donkey Kong but Mario just hits the ground. Donkey Kong Jr. carries his dad off-screen as Mario gets up and runs after them, only to be kicked right back out by Donkey Kong, forcing him to flee. In the NES version, this is altered to Mario falling to his apparent death.

Story from the Nintendo 3DS Virtual Console manual
"''Poor Donkey Kong™ has been captured by Mario™ and now finds himself locked up in a cage! It's up to Donkey Kong's son, Junior, to rescue him by snatching the keys to the cage away from Mario. Unfortunately for Junior, Mario won't give up those keys easily, and dangerous snapjaws, nitpickers, and sparks will attack him along the way. Will Junior be able to help his father...? That all depends on you!"

Gameplay
As a direct sequel, Donkey Kong Jr. retains many elements from Donkey Kong, although the two games are significantly different. While the original installment took place in a construction setting, Donkey Kong Jr. takes place in a jungle-like setting, from which Donkey Kong Jr. can climb up vines, drop fruit, or jump from place to place.

In order to free his father, Donkey Kong Junior must collect the key being kept at the end of each level, eventually using those keys to free his father in the end. All the while, however, Mario will sit near the Key as well as Donkey Kong's cage, summoning waves of monsters after Donkey Kong Junior from his position. After Donkey Kong gains a key, Mario will take Donkey Kong to the next location.

References in later games

 * Donkey Kong and Mario vs. Donkey Kong: Donkey Kong Jr., as well as many enemies and gameplay elements, make an appearance in this game (with Donkey Kong Jr. only being in the former). Also, Mario's method of trapping Junior in Donkey Kong '94 is identical to Donkey Kong Jr.'s method of freeing his father from captivity. Many enemies and gameplay elements from Donkey Kong Jr. are reused in Mario vs Donkey Kong as well.
 * Donkey Kong Country series: Diddy Kong and Dixie Kong's ability to climb two ropes at a time originates from Donkey Kong Jr. The music for this game is redone and replayed in the Golden Temple level of Donkey Kong Country Returns and Donkey Kong Country Returns 3D. A different cover of the song plays in the Secret Seclusion world in Donkey Kong Country: Tropical Freeze. The plotline for Donkey Kong Country 2: Diddy's Kong Quest was also very similar to Donkey Kong Jr., including Donkey Kong being captured by an old enemy (in his case, Kaptain K. Rool) and requiring that Diddy save him by traveling to the place Donkey Kong was being held captive.
 * Super Mario Kart: Donkey Kong Jr. appears as a playable character in this game.
 * Super Smash Bros. Melee: Donkey Kong Jr. appears as a trophy in the game, and his antagonism towards Mario is referenced in the flavor text for the trophy.
 * Super Smash Bros. Brawl: When Diddy Kong, Fox, and Falco arrive at the barge taking the recently-trophified Donkey Kong to the Ancient Island, Donkey Kong's trophy is shown in chains on the arms and legs, referring to Donkey Kong's captive status in the game, particularly the final level of the game.
 * Castlevania: Order of Ecclesia: The lightning trap room where the Vol Fulgur glyph is found is similar to Stage 3 of Donkey Kong Jr. and was most likely based on that stage.
 * Super Smash Bros. Ultimate: Donkey Kong Jr. appears in this game as a spirit. Additionally, a medley of songs named "Donkey Kong / Donkey Kong Jr." is featured.

Trivia

 * During the intro of the arcade version of Donkey Kong Jr., there were actually two Marios seen carrying Donkey Kong's cage away. This second Mario was possibly the basis for Luigi.
 * Most versions of Donkey Kong Jr., including the NES version, had the ending theme played once instead of twice. The three versions to break this rule were the Intellivision, Coleco Adam, and Atari 8-bit computer ports.
 * In the arcade version of the game, between the second and third stages, Mario carries Donkey Kong away in a yellow helicopter, with Jr. following close behind with a parasol.
