Donut Secret House

Donut Secret House is a secret level of the game Super Mario World. This level is the home of the Big Blue Boo, the miniboss who protects the Star Road. If the Mario Bros. beat this boss, they'll have access to go to the Star World. In order to find the secret door to reach the Big Blue Boo, Mario or Luigi must go through the first ghost door. Once through that door, you will encounter many doors that will lead you to exits for the level. There will be a P box waiting for you to access these doors. Note, it is necessary for Mario to have a feather to fly because this is how you will find the super secret door. When you get to the P- Box, press it. Mario must run up and fly. There was a secret key with a lock in this section, you must have already found the key to have the secret door appear. If you make it up to find the blue secret door, open it and it will take you to the Big Blue Boss. To defeat the Big Blue Boo, the player must pick up the grab blocks that make up the floor and kick them at the Big Blue Boo, without taking the floor away in the process. After the defeat of the Big Blue Boo, the player can access the first Star Road, which leads to Star World 1.
