Gravity Falls is the name of a joke skin, that was added February 14, 2016. SpongeOddFan used King Neptune for a Day and one of his requests was a Gravity Falls skin, which hilaryfan80 turned into reality. It was available to everyone for 24 hours during SOF's reign, and became a Loyal Customer exclusive skin afterwards. The skin was discontinued on August 15, 2017 with the release of Squid 12.
- This is the first time in SBC history that a user requested a skin to be made as Overlord.
