Our first 2 piggies, Badger and Beaver, were given those names for 2 reasons - firstly because of their colour, Badger being mostly black and white, and Beaver golden brown like a beaver, and secondly because my son (whose pigs they were) was at the time a member of Beaver Scouts and St John Badgers.
Our next pig, Yoshi, had been named after the SuperMario character - his cagemate Sonic had sadly died already, before his owners who were going abroad, took him to the rescue.
Zebedee also had his name when he came to us from rescue - though I can't imagine anything less spring-like than dear old Zeb !
Squeaks was a very vocal baby when we adopted him, hence the name there. In his case, we did change the name he had been given in rescue - they had called him Jackson, because he is black all over, except for one white paw, like Michael Jackson in one of his performances.
