I agree here, I would NOT put baby oil on a snake. That just sounds like a bad idea to me.
baby oil is made out of :
Purified Water, Mineral Oil, Cetyl Alcohol, Triethanolamine, Aloe Vera Extract, Fragrance, Calendula Extract, Vitamin E Acetate, Methyl Paraben, Chamomile Oil, Propyl Paraben, Butyl Paraben.
I can see like 6-7 things I wouldnt want to put on my snakes based off of that list.
