I would like to see the Snakes added to the tamable pets, we already can build altars of Set and summon the Avantar of the Snake god, so it would make sense if you play as a follower of Set to have some Snakes and maybe even giant Snakes guarding your Temples etc.
To get the Eggs I would suggest that you are only able to get them from an NPC, maybe from someone like Mek-kamoses or one of the NPCs in the Vulcano and only in exchange for Human Hearts to prove that you are real follower of Set.
They would come in 4 variants
Variant A & Variant B would both be Cobras
Variant C would be the middle-sized orange Anaconda you can find in the Dessert.
Variant D would be the Giant-sized Anaconda you can find in the Jungle.
Changed the name and some details of my posts to make it more clear what I mean.
