Hogwarts Giant Squid

The Giant Squid was a creature that lived in the Hogwarts Lake. Despite the generalised fear of it, the Giant Squid was actually very docile and helpful to the students of Hogwarts, such as when Dennis Creevey fell into the Lake, and he was immediately picked up by one of the squid's tentacles and put safely back in the boat. This squid is also known to play with and accept foodstuffs from students, such as when he received toast from Hermione Granger.

Behind the scenes

 * J. K. Rowling once joked that the Squid is Godric Gryffindor, one of the four founders of Hogwarts. This would make it the world's largest Animagus. On the eleventh hour of every evening, The Squid would rise from the lake and transform into Gryffindor, who would wander the school grounds before returning at sunrise. This cannot be considered canon, however, because Rowling was trying to make a point sarcastically.
