WINDLEY KEY, Fla. - A dolphin's toy that resembled a bomb scared spectators Wednesday and prompted officials at a marine park to call 911. A dolphin playing in a tank at Theater of the Sea surfaced with several items, including one that looked like a homemade bomb.

The toy in question was a softball-sized glass jar containing a black substance and covered by a white substance, the Monroe County Sheriff's Office said.

Authorities said about 15 people, mostly employees, evacuated the facility around 11 a.m. while the sheriff's bomb squad investigated, The Key West Citizen reported.
