List of Donkey Kong Land glitches
From the Super Mario Wiki
This is a list of glitches in the game Donkey Kong Land.
NOTE: Unless otherwise noted, all names are conjectural.
If Donkey or Diddy hits an enemy and gets knocked back with no visible ground below, the game will mistake the player for falling into a pit and will count it as an instant death, even if both Kongs are present.
In some levels, particularly jungle levels, there are Neckys that sit on platforms and spit nuts, hoping to hit the Kongs when they're below him. However, if Necky is on the top of the screen, the sound effect of spitting nuts can be heard, but no nuts are actually fired.
