Although is is confirmed to exist now, it was a cryptid for a long time. Mentioned in episode 5 by Doc and Drew Saturday they said that their last anniversary was spent in the stomach of a Giant Squid. Also it was seen in The Kur Stone:Part One in a cage of Argost's house. Also has been seen in one of Secret Saturdays posters.
- It is possible that Argost made a huge hole in the squid's cage filled with water, because squids can't survive on land when they're dry.
- Like most squids, these sea monsters can squirt ink agaisnt attackers and eat meat.
- Unlike most squids, they spend most of their time in deeper waters.
Meat: The Giant Squid is a carnivore like all squids.
