First, a baby grand piano mysteriously showed up on a Miami sandbank. A day after it was removed, a small table with two chairs, place settings, a bottle of wine and a chef statue appeared on the now-famous strip of sand.
The latest prank has left officials worried the sandbank could become a target for more mischief and they are warning such activity is illegal.
The Florida Fish and Wildlife Conservation Commission said anyone caught leaving items on the sandbank few hundred yards from shore will be arrested.
A 16-year-old art student admitted that he put the piano on the sandbank in Biscayne Bay as part of an art project, and a crew removed it on Thursday. The table for two has also been taken down.
