Desert Skull

""(...I'm just a pile of bleached bones. I can't talk.)""

- A pile of bleached bones, Earthbound

Whenever a show features or references a desert, savannah or other barren land, odds are good that a bovine cranium will be involved to set the mood.

Often accompanied by cacti.

Compare Ribcage Ridge, a sister trope.

 * Cars featured a variation of this: since all animals in their world are also vehicles, in the desert surrounding Radiator Springs, there appear to be rusted-up car parts lying among the rocks and cacti.
