25m is the first level in Donkey Kong and the first level ever in the history of Mario and Donkey Kong games.
The hazards that appear in this level include:
- Barrels: These are the main enemies in this level. Donkey Kong throws an infinite amount of barrels attempting to stop Jumpman (Mario). They can be difficult to avoid since they tend to go down the ladders without warning. Donkey Kong always starts off with a blue barrel that spawns a Fireball. That barrel most likely contains gas. The barrels, however, can be taken out with hammers.
- Fireballs: These enemies appear each time Donkey Kong throws a blue barrel into the Oil Drum at the very bottom of the stage. In this level, they pose a very little threat since they appear at the very bottom when Jumpman is nearly at the top already. They can also be taken down with hammers, and they can also climb the ladders.
- Donkey Kong: He is the main antagonist. Just running into him instantly defeats the player. This is rather rare since one will already climb the ladder to reach Pauline.
