Fliguiq

Fliguiqs are genetically engineered porcine creatures, created by an insane scientist with domestic problems. Apparently the scientist in question found the motivation to create this airborne species after a particular heated row with his common law wife, after she informed him that a pre-condition for her to make dinner when he came home was "When pigs fly."

FigglyWigg

A FigglyWigg is a strange crossbreed of snail, goblin, pigeon, and pig. Originally bred as a biological alternative to waste disposal, they have also become quite popular for their meat. The wings are small and vestigial, giving rise to the phrase "When FigglyWiggs fly."
