Swampy's Oasis is an area in The Desert which is fenced off by high sandstone walls and contains a large patch of vegetation inside. It made its first appearance in "Shadow of Israphel" Part 42: The Oasis. The Oasis belongs to Swampy Bogbeard.
The oasis is a huge rectangular shape in The Desert surrounded by walls of sandstone. Inside, it contains a massive tree (possibly where Swampy Bogbeard takes residence). There is also a river leading to a lake and a wooden bridge. There are some mushrooms in shady areas and some giant trees. When our heroes first got to the oasis, the trees were dead, the river was dried up and the ground cover was soulsand instead of dirt. Swampy was able to recover it by meditating on his tree.
Swampy's Oasis made its first appearance in "Shadow of Israphel" Part 42: The Oasis. In the episode, our heroes, accompanied by Shiplord Hubert, in hopes of finding a healer, traverse the desert, searching for this mystical oasis. When they reach the oasis, it is surrounded by a sandstone wall. Much to their surprise the oasis is withered and ruined. The heroes protect Swampy while he unleashes his magic from on top of his tree, slowly restoring the oasis to normal. Afterwards, the heroes depart with some of Swampy's healing herbs, to bring back to Professor Webley, while Hubert stays behind to recover.
