This underground chamber can't be seen or accessed during normal play.
Constructed as part of the level terrain itself, this scene appears to have been put together as a Bonus Area prototype, or perhaps an Item Cache testing room.
The six holes visible in the middle of the path look to be graphics for Item Caches. These may indeed be the only occurrence of such graphics within DKC's cave levels.

The 'Mincer Room'
This passageway seems a bit like a Bonus Area, but it differs in two key ways:
- There's no Bonus Area music
- It doesn't add to the game completion percentage
Interestingly — as with Bonus Areas — being hit within this room will not cause a loss of lead Kong/life, but will cause the room to be exited.
