Go to "Jungle Hijinxs!" which is the very first level. After you "pop" out of your house, go on the floor. Go to where the first "DK" barrel is. Jump on two the first "dirt hill". Wait near the edge until that little beaver goes past the "red flower". Bounce off of him and make sure you fly above the "DK" barrel. A LEVEL WARP should pop-up right next to that tree.
