Scintillating Jeweled Scuttling Crabs

Scintillating Jeweled Scuttling Crabs live on the planet Vogsphere, the Vogons' homeworld. Vogons enjoy smashing the crabs with mallets, and then eat them. Although the Vogons migrated to the Megabrantis cluster, the political hub of the Galaxy, every year the Vogons import twenty-seven thousand scintillating jeweled scuttling crabs from Vogsphere to smash.

When Arthur Dent lands his shuttle pod on Vogsphere in The Hitchhiker's Guide to the Galaxy, the door crushes a friendly crab.
