Mushroom Forest
The Mushroom Forest is an area in the Diablo Desert that has a lot more vegetation, primarily giant Mushroom trees.
Overview
Mushroom Forest
Monster Carrot's Village, Monster Carrot's Hideout, and Pilaf's Castle are located here. In the movie Dragon Ball: The Path to Power, Goku fights Oolong, and then Yamcha in the Mushroom Forest.
In Dragon Ball: Origins, it is a stage where Goku must look for Monster Carrot's Hideout and then defeat a T-Rex. It is also where he found the "Curvy Lady" he brought to Master Roshi. In the bonus level 5-6 in this video game, Nam was seeking food for his village after the 21st World Martial Arts Tournament when he ate a mushroom from this forest that made him unbearable; Goku must defeat Nam to reason him after he found him in Monster Carrot's Hideout.
In Dragon Ball Online, this area is called "Kinoko Rocks". It was taken over by the Paella Gang (a gang similar to the Pilaf Gang) in Age 988.
