Hidden Valley

Hidden Valley is a location in the Generation 1 continuity family.

Hidden Valley is secure from the prying eyes of humans in the the farmlands around it, a perfect base from which the otherwise conspicuious Dinobots can watch for Decepticon activity... or just relax and enjoy its delicious salad dressings.
