Sandcrawler

Sandcrawlers were giant dune buggies that Jawas used to gad about the surface of Tatooine. They were filled with junk picked up from all over the surface, including droids and leftover technology. Jawas didn't invent them. They were manufactured centuries ago by Czerka and then left sitting around.

Sandcrawlers could be violently shaken to create Jawa juice.
