Story behind this piece
King Snout was a king and was also an actual pig. King Snout was crowned by the people because Prince Percival told the citizens that they should crown a pig instead of him so "that they could be ruled by their own kind". The citizens took Prince Percival's word and so crowned a pig, later named King Snout. King Snout reigned over the people for six happy and peaceful years.
