Razor Reef is the fourteenth level of A Koopa's Revenge 2, or AKR2 for short. It is the first underwater level in the game.
- There is a secret exit in the level that leads you to World 3-3.
To get there, near the end of the third part of the level, where you see free space below the terrain, swim under it. Get out of the water and then jump over the large gap, where the secret flagpole will be right there.
