LONDON (AP)–Harry Potter author J.K. Rowling has clarified that slain Ohio gorilla Harambe is not a part of her fictional universe.

A new feature on Rowling’s Pottermore website allows users to find out what Patronus they would use in Harry Potter’s world. A Patronus is an animal used to ward off soul-sucking creatures in the series.

Humor site The Chive put a fake picture on Twitter of Harambe the gorilla as a result on the Patronus page. Rowling retweeted the picture. A bit later she posted , “I’ve been asked to make it clear that Harambe is not a Patronus you can actually get on @pottermore.” But she added that she thought the joke was “very funny.”
