Iguanas are an invasive species in Florida, causing problems for the state’s environment, but one South Florida city has felt the impacts of the reptiles more directly after one caused a large power outage.

According to the city of Lake Worth Beach, an iguana caused a large-scale outage December 7th at a substation on 6th Avenue.

The city did not say exactly how the lizard caused the outage. It was reported by another source that the iguana hit a transformer with its tail, causing the outage and killing the reptile.

The utility company’s outage map shows everyone is now back on the grid.
