Progressing, we already make it to the Star World. These are the levels shown in this part:
Donut Secret House (Secret Exit): Go through the same path as earlier, but instead of taking the blue door after hitting the P-Switch, go under the blocks of the brown door, then hit the center one. A vine will grow. Climb up the vine to reach an area with a new door. Enter it to have a boss battle against a Big Boo. To defeat him, pick up the Grab Blocks that make up the ground, and throw them up at the Boo. Three hits will defeat him. Defeating this boss will lead you to an entrance to the Star World.
Star World 1 (Secret Exit): This level consists of mainly Spin Jumping to destroy blocks. I'll show the Normal Exit for this, and the other forgotten ones later. For the secret exit, keep Spin Jumping on the right side. You will find a Key next to a Keyhole. Pick up the Key, and run into the Keyhole. This level contains a Red Yoshi, taking the normal path.
Star World 2 (Secret Exit): A simple underwater stage filled with many Blurps and Rip Van Fishes. This level is easier with Yoshi, but you just need to simply avoid a bunch of fish. For the secret exit, instead of taking the pipe, swim under the exit to find a Key and a Keyhole. Carry the Key into the Keyhole. This level contains a Blue Yoshi.
Star World 3 (Normal Exit): Since this level is so short anyways, I decided to do the level in general. Just run to the right, avoiding the Lakitu, to beat the stage. This level contains a Yellow Yoshi.
Star World 3 (Secret Exit): This is easiest to do as Cape Mario. Just fly upwards to find the Key and the Keyhole, and simply exit the stage.
Star World 4 (Normal Exit): This level contains many Koopa Troopas and Koopa Paratroopas. This is a good stage to test out Yoshi's skills with the shells. This level contains a Red Yoshi.
Star World 4 (Secret Exit): Later in the level, eat a Blue Shell so you're able to fly. Now, fly under one of the later platforms, and you should see one that has a Keyhole and a block on the ground. If you have the shell in your mouth still, spit it out at the block. If you don't, whack it with Cape Mario. A Key should come out. Carry the Key into the Keyhole.
