Valley of Bowser 4

Valley of Bowser 4 is the fifth level of the Valley of Bowser in Super Mario World. This level can be accessed through the completion of the level Valley of Bowser 3. There are Chargin' Chucks with shovels that throw rocks called Diggin' Chucks, red-shelled Koopa Paratroopas, some Spike Tops, and Cheep Cheeps.

Overview
In the beginning, there is a Diggin' Chuck and a red-shelled Koopa Paratroopa. After that the player will find another Diggin' Chuck next to a blue Warp Pipe and a Yellow ! Block. Then there is some lava and more Koopa Paratroopas, followed by a green Warp Pipe and a ? Block that contains a Vine. If the player goes down the Warp Pipe, there will be an icy cavern with one Dragon Coin, a few Spike Tops and Cheep Cheeps that swim in the water. There is also a ? Block that contains a Super Mushroom or a Cape Feather. On the other side there is another Warp Pipe that backtracks to the blue Warp Pipe that they saw before.

Up the Vine, the player will find a ? block that contains a Yoshi. The player can either choose to dive down the small pit, or to break the Rotating Blocks to go down. There is a hidden 1-Up Mushroom if the player chooses to go down the yellow blocks. Later, the player will find the Midway Gate, and many more Diggin' Chucks.

There is a Key encased in a closed off receptacle inside of a wall just before the exit. The Key can only be obtained via Yoshi's tongue to grab it through the wall. The Keyhole leads to Star Road, Star World 5 and the Front Door of Bowser's Castle. If the player chooses to go through the Giant Gate, they will gain access to.
