On Vogsphere, the Vogons would sit upon very elegant and beautiful gazelle-like creatures, whose backs would snap instantly if the Vogons tried to ride them. The Vogons were perfectly happy with just sitting on them. Another favourite Vogon pastime is to import millions of beautiful jewel-backed scuttling crabs from their native planet, cut down giant trees of breathtaking beauty, and spend a happy drunken night smashing the crabs to bits with iron mallets and cooking the crab meat by burning the trees. In the movie, the Vogons seem to smash the crabs for no apparent reason besides pure pleasure at killing something.
