Donut Plains 4

Donut Plains 4 is the last level of the Donut Plains in Super Mario World, just before Morton Koopa Jr.'s castle. Since this stage is out in the open, it is a suitable place for the Koopa Troop's aerial force to attack. Therefore, Mario meets there for the first time the airborne counterpart of the Hammer Bro., known as the Amazing Flyin' Hammer Bro., as well as a squadron of Paragoombas.

Interestingly, the two versions of Paragoomba can be seen in this level: the Goomba paratrooper, who only appeared in Super Mario World, and the Winged Goomba, who was called Paragoomba in other Mario games.

Enemies

 * Goomba
 * Koopa
 * Jumping Piranha Plant
 * Paragoomba

Secret areas
There are two secret areas in this level; both can be reached using 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 will lead him to a small area with two Parakoopas; the player must then jump on green pipes to cross the pit, and reach another pipe to exit the area. However, this area is rather worthless since no bonus can be found in it.

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 6 Coins as well as a Yoshi Coin.

Exit
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 Bro., then jump onto his flying platform.
