25m in the Game Boy version

25m (or 25 m) is the first level of the Donkey Kong arcade game and Donkey Kong on the Game Boy. It is the bottom level of the Construction Site. The level starts with Donkey Kong capturing Pauline, Mario's girlfriend. The player takes control of Mario as he jumps over barrels and climbs to the top of 25m, where Donkey Kong and Pauline are located, via a series of ladders. Mario also finds hammers around the area, which he uses to smash the barrels. After reaching the top of 25m, Donkey Kong grabs Pauline and climbs up to 50m. The bottom of the level also features an oil drum. If a blue barrel enters the oil drum, it creates a Fireball that tries to hunt down Mario. If there are five Fireballs simultaneously onscreen, Donkey Kong stops throwing blue barrels, and any remaining blue barrels do not create a Fireball unless Mario thins their number.

In the original arcade game, an intro segment shows Donkey Kong climbing to the top of the Construction Site with Pauline under his arm, then jumping along the top platform to cause the broken ladders and sloped girders that make up the level. It was cut, along with most of the cutscenes and the 50m level, in the original NES version, but was eventually restored in the Game Boy version.

In the Game Boy version, two layers of platforms are removed due to the handheld's small screen. A later level, Stage 9-5 in the Tower, retains the exact appearance of the original 25m by employing a scrolling screen.

Appearances and references in other games[edit]


Donkey Kong storming off with Pauline
  • This is the only level in the game that does not feature Pauline's lost items.
  • A glitch in the earliest arcade version allows Mario to complete the level by jumping from the first girder to the floor below which causes him to fall through the floor. This registers him as beating the level.
  • A similar glitch can be found in the NES version. If Mario is positioned at a certain spot on the first fixed ladder, he could climb down and wraparound through the top of the screen to end up at the top girder.
  • A glitch found in the NES version and all but the final international arcade revision causes barrels to not roll down his ladder if Mario's hand is touching the top of the girder.
