Goodwill Donations workers got more than they bargained for after unpacking a donation box filled with books and one four-foot slithering snake.

The Stafford Sheriff’s Department in Virginia announced the donation box that sprang to life in a social media post filled with Harry Potter references on Tuesday, June 18.

Animal Control Capt. J.A. Bice was called to the Goodwill store to remove the unwanted donation after workers stumbled across the snake.

The snake, identified as a 4-foot-long basilisk, was found among a donation box of books, police said.

“Using his powers of persuasion, and a bit of Parseltongue, Captain Bice was able to safely remove the snake and release it back into the wild,” police said.

The sheriff’s office did not reveal the species of the “Slytherin suspect seized” at the store, but said it was likely a reptile in search of shade amid the heatwave impacting the region.
