In Kongo Jungle the first area of the game goto the second level which is Ropey Rampage, in this level you can find a level warp barrel. The location of this barrel is off the edge of cliff on the other side of the first rope which you would usually climb. Theres a armadillo underneath the rope and a TNT barrel behind you if you havn't thrown it yet. What you do is jump over the edge of the cliff onto the first flower you see.

Example: -----|---   *

The - is ground, | is rope, and * is the flower.
