One blue boi. (da ba dee da ba die.)

Description: |Blue signifies trust, responsibility, honesty, loyalty, and inner security.| Blue Sans, or better known as Cobalt, is one of those skeletons you can trust. Whether it be keeping a secret, or remembering to feed your cat while your out buying Fortnite or some shit. He will never lie to you, ever. He'll stay true to his word if he says he'll do something. He'd put his life before someone whom he promised to keep safe.
