Oscar is a lizard living in a non-specific desert that has features from several different real deserts, like the Sahara, Kalahari Desert and North American deserts. An asphalt concrete road runs through the area, and it is occasionally used by various trucks. A lot of garbage litters the desert, and the main characters are constantly exploring it. They find amusement with the different pieces of litter they encounter. Oscar is usually searching for water or food for himself while his friends sometimes help or hinder his search. He sometimes finds liquid in bottles or the ground but is not successful in recovering it to drink. Oscar will sometimes eat eggs he usually tries to steal for from a hen house nearby. Three unusual friends also camp in the area: Popy - a desert fox, Buck - a vulture, and Harchi - a hyena. They live in a derelict school bus. The desert has deep canyons and the main characters often find themselves falling down in same matter as Wile E. Coyote when chasing the Road Runner.
