Pan's Labyrinth Cameo by Frog of Cthulhu

I know we don't watch Pan's Labyrinth until next week but I couldn't help but post this. I was rewatching Pan's last night when I saw that intense and kind of gross scene with the giant tree frog and I was immediately reminded of the giant toad in "The Black Stone". It had me curious if there was some giant dark fantasy conspiracy going around to make frogs even creepier than they already are. Makes me wonder what has these people choosing frog's as these mythic disturbing creatures. I dont know if it has anything to do with frogs being one of the Lord's plagues on Egypt and these writers are just running off that supernatural vibe or what. I just thought it would be a neat topic of discussion.
