The Fantastic Beasts house names may just have leaked

Every Harry Potter fan knows which Hogwarts house they belong to, but what about the houses at the US version of the magical school? (Note: There are spoilers ahead).

Ahead of the upcoming Fantastic Beasts and Where to Find Them, fans are scratching for information about Ilvermorny - America's Hogwarts - and now they might have some.

According to the Daily Mail, a man called Federico Ian Cervantez accidentally stumbled across the names of the school's four houses while examining the javascript for a new quiz due to appear on the official Harry Potter website, Pottermore.

The quiz apparently begins with this intro: "Where do you belong? Horned Serpent, Wampus, Thunderbird, or Pukwudgie".

The Horned Serpent is later described as "dragon-like serpents with horns and long teeth", said to be able to control the weather, shape-shift, turn invisible and hypnotise.

The Wampus is a "fearsome", "cat-like" creature, and the Thunderbird is a "legendary creature", "described as a very large bird, capable of generating storms and thunder as it flies".

And the Pukwudgie is said to be "human-shaped, but with a larger nose, ears, and fingers and smooth, grey skin that sometimes glows. Its magical abilities include disappearing and reappearing, partial or complete transformation into a porcupine or cougar, and creating fire".

Cervantez shared his discovery on Reddit, and wrote a blog post about his findings, including screenshots of the code.

In the blog he also said if he had accidentally caused someone at Pottermore to lose their job over the discovery, he was "truly very sorry", adding if that was the case, "contact me - we might have a place for you".

Fantastic Beasts And Where To Find Them, stars Eddie Redmayne, Colin Farrell, Katherine Waterston, Alison Sudol and Ezra Miller.

It is due for release in November.
