Sandy is the cousin of Randy, Earl, and Sandy Cheeks.
Sandy bears a strong resemblance to Sandy Cheeks, except for the fact he is wearing a plaid kilt, with a hat to match, and looks quite older than her.
Sandy can play the bagpipes.
When Sandy was an adult, he went to Bikini Bottom to get a job at the Krusty Krab. He was not accepted. Stanley S. SquarePants, cousin of SpongeBob SquarePants, was accepted instead.
