Knight Bus: a magical bus that appeared whenever a witch or wizard was in urgent need of transportation, all they had to do was stick a wand arm out at the curb for it to instantly appear. Distinctive in appearance, the Knight Bus was purple and triple-decker with seats during the day and beds at night. --WizardingWorld.com, covering the British series Harry Potter
