Super Mario World/Yellow Switch Palace

The Yellow Switch Palace is the first of the four switch palaces in Super Mario World.

Entrance

 * Yoshi's Island 1

Walkthrough
Yellow Switch Palace is a very easy level with a 200-second time limit. It consists of two rooms connected by a single green pipe. The first room contains a P-Switch and a long ledge of concrete blocks. Stomping the P-Switch will cause coins to materialize temporarily everywhere in the room. Collect as many as possible to gain extra lives. After the switch wears off, enter the green pipe on the right end of the room.

You will now enter a long corridor that terminates in a room with a large, yellow switch marked with an exclamation point. Jump on this switch to receive a message that all yellow block outlines have become filled in. This message will end the level. On the overworld, a series of yellow blocks with exclamation points will fly out from the palace, and the palace will then explode. You will receive a prompt asking whether or not you want to save your progress. The level will not be henceforth accessible.
