I thought I should leave something here seeing as last night I was of a "no time for leaving a message for the seller I must buy NAO" sort of mind. As soon as I saw the little Sobit I dove for the credit card. Well, that is after I did a little happy dance and realized I had money which caused more happy dancing until it got to be time for So thankies for cheering up my sick self.
Nup, you're thinking of Ammut/Ammit Devourer of the Dead the crocodile-lion-hippo personification of all that was not Ma'at. As with all Egyptian gods Sobek was many things to many people and he and Anubis sometimes played duty juggling but mainly he was seen as a protector of Pharaohs and one of the gods of fertility and of course appeasing him was a way to gain protection from his sacred animal the crocodile.
