Gimlick Valley was a valley in the planet Morklon. The notable Battle of Gimlick Valley occurred on it. It was a derelict, dead and toxic place when Ratchet had first visited, but after saving the Fongoids from dying off, the place became vegetated like it always was.
Fongoids lived within this valley, in the Eurandi Outpost. The water there was once pure, but after the invasion of the Agorians, the water there became infected and dirty. After time changing, the water came back to its pure state.
