I am assuming you are asking what the source of Sleestaks is.
The answer is, Land of the Lost, an old live action Saturday morking series where a family gets lost in a land filled with prehistoric creatures, and the Sleestaks are villainous lizard thingies, some with access to some wierd magic/technology.
