Bat Damon is named by Peter Griffin after a bat gets into the Griffin home in "Hot Shots".
Determined to get the bat out, Peter tries several stunts like attaching knives and a gun to a drone, without luck. Late one night, he pursues it with a tennis racket, smashing his way through the house until it lands on Stewie's head. Peter tries to smash it again, but ends up striking Stewie.
Bat Damon joins several other animals of the show as well as the cast in singing "Blue Shadows On The Trail" in "Wild Wild West".
