Mondo

Mondo is the sixth level of the Special Zone in Super Mario World. At first glance, it looks like a normal level, with a few platforms and pipes; however, Mondo actually has a special feature: water tides, which constantly rise and lower.

Overview
Mondo consists of one long area, a short screen with the Giant Gate, and an optional area down a blue Warp Pipe. This level has five Dragon Coins, and it allows the player 300 seconds on the timer to complete. Although Koopa Troopas and Jumping Piranha Plants can be seen in Mondo, the most common enemies here are Cheep Cheeps. Without water, these fish flop around erratically, but when the level is flooded, they swim as they usually do.

Normal exit
The player must be very careful, as the way of crossing the level depends on whether there is water or not. For instance, there are two ways to reach the top of a high pipe; the player can either use the Flying Platform of an Amazing Flyin' Hammer Brother as a lift or swim over the pipe when the level is flooded. A Cape Feather can be found in the first Prize Block if Mario or Luigi is big, or a Super Mushroom if he is small. Yoshi can be found in a Prize Block as well. The end part of the level contains a bunch of Prize Blocks, which mostly contain coins. The player is given the option to save after this level. Using a Cape Feather, if Mario or Luigi waits long enough at the beginning of the level for the water tide to drop below the ground, he has enough running space to take off and fly over the level to the Warp Pipe leading to the Giant Gate. This requires steady timing, however, as the player has to press Left on almost rhythmically to keep above the Amazing Flyin' Hammer Brothers, as the second top half of the level constantly stays offscreen.
