Super Mario World/Vanilla Secret 3

If you have Yoshi or fireballs this level should be a breeze. Otherwise you will need to get through this partially water-logged level on the back of flying fish. About halfway through the level a large spiked fish appears and attempts to stay directly below you. Yoshi can land on it or a single fireball will knock it out. Then scurry on to the end.
 * There are some flying fish that will alternate from one position to the other. There are also some that will leap forward, some backward, and some that stay in one place.
 * If you are caped, you can simply fly over the whole course if you want.
