75m

75m is the third level of the original Donkey Kong (second in the NES version). It is also known as the "Elevator Level" due to the unique elevator-based gameplay that takes place on this stage. This stage would later be revamped into a stage for the game, Super Smash Bros. Brawl.

Original Donkey Kong
This level has many unique features. First off, two elevators appear in the level for Jumpman to use. This level contains many small segments of landable areas on the construction site, so timing jumps is key. If Jumpman jumps off the elevator and has too much air time, when he lands, he will lose a life. A Trouble Bug will greet Jumpman on the second platform, which calls for careful timing on when the player should land safe of the fireball. After, the player can either grab Pauline's hat, guarded by the Trouble Bug, or choose the safer option and get to the second stream of elevators.

After getting past the two elevators, Jumpman's troubles will not end there. Donkey Kong, out of barrels, will toss bouncy and dangerous springs towards jumpman. They do go in a pattern, but are still somewhat unpredictable. The second trouble bug is to the far right guarding Pauline's purse. This level overall is rather annoying and tight, but practice and studying the timing of the springs will ease the level.

Super Smash Bros. Brawl
75m would also make a reappearance decades later (aside from remakes) in Super Smash Bros. Brawl as one of the unlockable stages, under the name 75 m. In order to unlock the stage, one must play as Donkey Kong in 20 brawls. Despite other "retro" stages in SSBB being 2-D, 75m's platforms were given 3-D depth. Trouble Bugs, the ladders, Pauline's items, and retro Donkey Kong are rendered as sprites however.

The stage retains the tight feel from the arcade version, but the far right has been extended for Brawl's fighting gameplay. The ladders are climbable and Pauline's items are collectible as well, and even add up to a "high score" at the top of the stage (though does not directly affect gameplay nor do the points carry on to future Brawls). Trouble Bugs count as moving enemies and will hurt and burn a Smash character on contact. A retro render of DK will appear in his usual spot, occasionally coming out and tossing springs as he would in the original. Retro DK is invincible and contact will greatly hurt a fighter, and the springs themselves are deadly.

Aside from a stage, the NES version also appears as a masterpiece demo in Brawl.
