The Thetis Lake Monster is a legendary creature and admitted hoax of Victoria, British Columbia, Canada.
On 22 August 1972, the Victoria Daily Times reported that two local teen boys claimed to have seen a creature with "silvery scaled skin, sharp claws, and spikes on its head" while swimming at Thetis Lake beach in the evening.
However, when writer Daniel Loxton contacted one of the individuals years later, he admitted they had fabricated the story to get attention.
According to Loxton, "local TV had shown a movie about a scaled humanoid gill-man attacking teenagers at the beach after dark.
Four days later, local teenagers reported being attacked at the Thetis beach after dark by a scaled monster".
