I guess they made the naughty list.

More than 60 people were injured on Christmas Day when a school of piranha ripped through them in the waters off Parana River beach near Rosario, Argentina. Seven children were injured in the attack with one very unlucky seven-year-old girl bitten so badly that part of her finger had to be amputated.

Paramedic Gustavo Centurion stated the obvious to when he said that the piranhas were “very aggressive.”

The attack is being blamed on warmer than usual temperatures.

The beach is closed to swimmers for the time being.
