This level has 2 exits, when you get to the end, there is a blank yellow box, the kind you can break. Hit this and a vine appears, climb up this vine for the normal exit. For the alternate exit you need a cape or a blue yoshi. Right after the yellow box with the vine is 3 arrow signs, fly in that direction and dont stop flying till you're gone past the goals.
