Ozzy Osbourne's Bat Skull

Origin
On January 20th, 1982, 17 year-old Mark Neal threw a live bat onto the stage of Black Sabbath concert in Des Moines, Iowa. Clearly hoping for a repeat of the dove incident of the last year, his wish was granted when frontman Ozzy Osbourne took the bat and bit its head off on stage.

In later years Ozzy would go on to clarify that he thought the bat was rubber before he bit it and that before it died it bit him back. This incident went on to become one of the most infamous and most referenced Rock music legends of all time.

Effects
When exposed to Black Sabbath music, the skull will animate and fly directly towards the mouth of anyone singing along. The skull will attempt to bite down on the tongue, and is difficult to remove.

It was collected after a diehard Sabbath fan purchased it at an auction, whereupon it savaged him and his partner as they played some Sabbath records on the aniversary of the incident. It now resides in a soundproofed glass case in the Rock section of the Music Aisle.
