Go to the first level that has carts that ride on the rails. If you don't have both Diddy and DK, bust the barrel to get them. Right at the beginning of the level, there is a barrel that you have to jump into to get shot into the cart. Have Diddy jump right beside the left of the barrel right at the ledge. Turn him so he is facing left, and then switch to DK. if done correctly, one of the two will go onto the barrel and the game will freeze.
