Super Mario World/Top Secret Area

The Top Secret Area can be accessed through Donut Ghost House on the second island of Super Mario World. The top secret area contains 5 yellow switch boxes. The first 2 are fire power and the second 2 are feathers. The middle box contains yoshi. If you go to the top secret area and are small the first box you hit will be a mushroom (with the exception of the middle box.) If you go to the top secret area and already have yoshi, you will get a one up mushroom when you hit the middle box.
