World 4-1 is a level found in New Super Mario Bros. This is the first level that introduces Dorrie.


Mario riding on Dorrie.

This level is a forest with poisonous water underneath, and the level introduces Scuttlebugs as common enemies in this level. After the Checkpoint Flag, Mario or Luigi can ride on Dorrie to traverse through the level.

Secret exit

While Mario is riding Dorrie, the player should notice that on the way, there are two ? Blocks with three normal blocks in between. If Mario gets on top of them and jumps in the middle, a Beanstalk will come out of a Hidden Block. Mario must climb on it and enter the pipe to reach the Red Flagpole. The secret path opens up a 1-Up House, and World 4-Tower.
