Frog Valley, also called "The Valley," is one of the main regions of Amphibia where Wartwood Swamp is located. As the name suggests, it consists of small towns situated within large mountain ranges and cliffs. According to Hop-Popular, there are 22,651 amphibians living in the valley. Through its yearly course, the valley's boundaries freeze up and remain inaccessible for a period of time, in which travel in and out of the valley is impossible. Only once the ice thaws, can trips and travel resume.
- The frozen boundaries of the Valley is first shown in the episode "A Night at the Inn".
