Instructions
Walk over to the elephant ride in the middle of the park. Face one of the smaller elephants that are lower to the ground. Jump on the back of the elephant by pressing the "A" button.
Jump to another, taller elephant on the ride. While running off the head of the first elephant, press "A" to jump toward the back of the second elephant.
Press "A" while you are at the height of your first jump. This will make Mickey perform a second jump in mid-air and will give you enough distance to make it to the second elephant. Continue jumping from one elephant to the next until you reach the tallest elephant.
Walk to the wing of the elephant so that you are facing the front of the tent. Perform a double jump again to land on top of the tent.
