Trivia [ ] A male goat is sometimes called a "billy" or "billy goat".
The idol of Billy is probably a reference to Billy Idol . When spotted, the following message is shown: "You have found the Billy idol."
Alternatively, a young goat is called a "kid". It is possible that it is a reference to the noted 19th century gunman known commonly as Billy the Kid .
