City officials in Amarillo, Texas are asking for the public’s help to identify an unidentified “object” caught on a security camera outside the city’s zoo.

The city posted a photo on their official Facebook page of what could be an oddly dressed person. They captioned the photo, “Is it a person with a strange hat who likes to walk at night? A chupacabra? Do you have any ideas of what this UAO — Unidentified Amarillo Object could be?”

The person or object never tried to get inside the zoo and police said nothing was vandalized.
