कीवर्ड Underground Cavern

There are some places on earth where the land just seems different, and Blind Frog Ranch in eastern Utah is one of those places. Locals say the land is cursed. That it's trying to hold on to something.

The Secret World of Og is a children's adventure about 4 children who venture into an underground cavern beneath their playhouse to look for their lost baby brother. There, they discover a land of little green people who are enamored by the world above but won't allow anyone to leave their cavern for fear they might "tell".
