We can't have the sons just have all the fun, can we? Here's Cthulhu hanging out with his beloved daughter (and backup plan in case something actually kills Octodad) Cthylla. I know that Cthylla's really is a giant red octopus with six eyes and wings, but this wouldn't the first time that the Great Old One were portrayed as anime girls.

I have plans for Cthylla with Housamo's Nyarlathotep with her trying kill him for screwing around with her Daddy's plans. Cthulhu is in Housamo but as a part of the 27 souls that make up the Protagonist (sounds weird). I hope we get more Lovecraftian summons in TAS.
