Oooohh yeah that definitely does look like a kink. Did the seller inform you of it???? I would definitely have an issue with them if they did not. However a kinked snake, even ones that are horribly kinked, much worse than that, can live a healthy life. Ralph Davis did a video on some of his caramels that are terribly kinked that eat fine, get around ok and overall seem fairly healthy.

It's up to you what you want to do but I would most likely be asking for my money back.
