Donut Plains 4

Donut Plains 4 is the last level of the Donut Plains in Super Mario World, just before #2 Morton's Castle. This level debuts the Amazing Flyin' Hammer Brother, Para-Goombas and Flying Goombas. The level has a grassland theme and mountains in the background.

Overview
This level consists of one long screen, which the player has 300 seconds on the Timer to complete.

There are two secret areas in this level; both can be reached using blue Warp Pipes. To get to the first secret area, the player must enter the blue pipe located near the beginning of the stage, avoiding the Jumping Piranha Plant. It leads him to a small area with two Koopa Paratroopas; the player must then jump on green pipes to cross the pit and reach another pipe to exit the area.

The second secret area is located farther in the level. Once again, the player must enter a blue pipe to reach a tiny underground area. In the small cave, the player can collect coins as well as a Dragon Coin.

The Giant Gate at the end of Donut Plains 4 can be found beyond a large pit. The only way to reach it is to knock down the nearby Amazing Flyin' Hammer Brother, then jump onto his flying platform. The player can also fly over there by using a Blue Shell or simply a Cape.

A Roulette Block and a 3-Up Moon can be found in this level as well.
