Land of the Lost (1974), Follow That Dinosaur
The Marshalls area awakened one morning by the ruckus that Grumpy is causing at the entrance to their cave. They come to the realization that it is because they constructed a curtain to the cave to keep out flies, the material used being the dinosaur equivalent of catnip to cats. So they decide what would be a good thing to do would be to get rid of all the “dinosaur-nip” as Holly calls it. In the process of pulling out and getting rid of all the dinosaur-nip, Will and Holly come across what they initially believe is a dead human body, but what turns out to a be a stuffed replica of a human made out of dinosaur-nip. The Marshalls are buoyed by the probability that an actual human made it. Indeed, Rick finds attached to the dummy a partial diary written in English. The diary ends up being a road map of sorts by its writer, a human, to what the Marshalls hope is the way out of this land and back home. But they first have to find the remainder of the diary, which entails not only dealing with Grumpy and Alice, but also the Sleestak, who they hope are still in their dormant stage.
