Land of the Lost - S01E01 - Cha-Ka

Rick, Will and Holly have just arrived in where they don't know, but which is a land inhabited by dinosaurs among other creatures that have long gone extinct or have evolved into other creatures. Rick knows they have to be most careful of the flesh eating tyranosaurs, one who they not so fondly nickname Grumpy being after them. As Rick goes off to try and find a safe route back to the cave where they have made their temporary home, Will and Holly spy a family of ape-like creatures. The smallest and probably youngest of the three creatures fractures its leg, and Will and Holly save it from being eaten by Grumpy. They learn the creature's name is Cha-Ka, and is a pakuni. As Will, Holly and eventually Rick try to nurse Cha-Ka back to health so that he can return back to the other pakuni while protecting him and themselves from Grumpy, they also try to make it clear to him that they want to be his friend. But will their actions translate into the type of friendship that Cha-Ka will ... Written by Huggo
