The Giant Squid was a creature that lived in the Great Lake, on the grounds of Hogwarts Castle. Despite the generalised fear of it, the Giant Squid was actually semi-domesticated, and, as such, was very docile and helpful to the students of Hogwarts, such as when Dennis Creevey fell into the Lake, and he was immediately pushed safely back into the boat. The squid was also known to have played with students, such as when Fred Weasley, George Weasley and Lee Jordan tickled its tentacles as it was lying part way out of the lake, and to have accepted food from students, such as when it received toast from Hermione Granger.
Early on in his time at Hogwarts, Ronald Weasley thought Tom Riddle may have received his Special Award for Services to the School for saving a teacher from the squid, and in his fourth year, half-jokingly expressed his hope that there was some chance the squid would harm Viktor Krum, who was bathing in the lake. Needless to say, Riddle's award had nothing to do with Hogwarts' Giant Squid, and Viktor was unharmed, as the squid was demonstrably not a threat to anyone.
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.
- The Giant Squid has not appeared in any of the Harry Potter movies. However, it was originally set to make a brief appearance in Prisoner of Azkaban during the scene where Harry rides Buckbeak over Black Lake, as evidenced by an early script.
