Get to the Vine Valley world's Vulture Culture stage.

Very important to have all of the two monkies and You have to lead by Donkey.

Grab the barrel and immadiately throw toward the Mini Necky, and run until the end of the platform and jump to the barrel. As it got the right position shot yourself out and jump to the automata barrel at the next cove. When You arrived to the new barrel immadiately shot Yourself out as it got the position and run under the necky. Now You are at the third cove, and if You were fast enough You will see an automata barrel at the edge below the other barrels. This will transport You to the end of the stage, to the board with the red arrow. But don't forget You missed the bonus stages...
