The Pharoasent The friendly jewel eating serpent

Deep in jungles and deserts you find temples in side you find loot of all sorts but then you hear not a hiss nor a rattle but a chirp you turn to find a coiled gold or emerald serpent with big sapphire eyes and redstone dust on its back called the Pharoasent which is a small serpent that resides in jungle and desert temples. The Pharoasent is a passive mob that loves shiny things and when I mean love it eats, that's right this gold boy eats jewels like diamonds and emeralds ( but it does eat small mobs as well) making it tameable but what does this serpent do well when coiled on your head it gives amunnity to poison (maybe withered) making it a cute but useful pet. With serpents being seen as evil this would be a good change for minecraft and for how we see our serpents in irl.
