Top Secret Area

The Top Secret Area is a hidden area filled with power-ups that Mario and Luigi can use in Super Mario World. The area is situated behind the Donut Ghost House, and it is unlocked by finding the secret exit in that Ghost House. This level functions similarly to the Toad Houses, and leaving the level will not end the player's turn.

In the original Super Nintendo Entertainment System version, the Top Secret Area has a yellow space on the world map, but in Super Mario World: Super Mario Advance 2, a smiling, blushing green hill is shown instead.

Overview
The level consists of a single area with five Prize Blocks. The two Prize Blocks on the left hold Fire Flowers, and the two on the right hold Cape Feathers (when Small Mario or Small Luigi hits the Prize Blocks, he will get a Super Mushroom first). A Yoshi Egg will appear when the center Prize Block is hit (a 1-Up Mushroom appears if the player already has a Yoshi). This level contains no enemies, and it can be accessed an infinite number of times, allowing Mario and Luigi to acquire the maximum number of extra lives. In the original version, the Top Secret Area has no time limit, but in the Game Boy Advance remake, there is a time limit of 200 seconds. All Yoshi colors are available in the remake except in the Japanese version, depending on the specific power-up Mario or Luigi has. The player can leave the area through either the left or the right exit.
