25m
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 in the latter game. 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 Fire that tries to hunt down Mario. If there are five Fires simultaneously onscreen, Donkey Kong stops throwing blue barrels, and any remaining blue barrels do not create a Fire 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 Nintendo Entertainment System versions, 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.
