JK Rowling has taken to Twitter to inform keen readers that they cannot have Harambe as a Patronus.
On Thursday, Harry Potter website Pottermore allowed fans to find out what their Patronus - a mystical animal caused by a spell which echoes your personality - is.
Some were unhappy, expecting to get a magnificent stag and ending up with a shrew.
Others were hoping their Patronus would be a gorilla, like Harambe, the animal Cincinnati Zoo killed after a child fell into his cage.
