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.
- Sandy looks similar to the Scottish Fish.
- This character is shown to be a Scottish relative of Sandy, possibly meaning that her relative lived in Scotland and Sandy lived in Texas, or the relative lived in Scotland before moving to Texas.
