Sandals is an olive-green background fish who first appears in the episode "Patty Hype."
He is an olive-green-colored fish with dark yellow-orange lips, light olive-green fins, and has dark olive-green spots on the side of his head. He wears purple shorts with white flowers and light blue sandals, which gave his name. However, in the first movie, he is seen wearing brown shoes and socks. He sometimes bears a striking resemblance to Scooter. In SpongeBob SquarePants 4-D: Ride, he appears in a greener color and wears red shorts.
He usually is a surfer at Goo Lagoon and doesn't act very intelligent.
He is best known for comedic one-liners, yet unlike fellow popular/common background characters Tom, Fred, Harold or Nat Peterson and his weak speaking voice, he has not gotten any plot impacting roles in any episode (as of writing).
Sandals is very picky about what he eats, as seen in the episode "Clams."
Sandals is allergic to pickles and will swell up and explode if he eats them.
In the episode "The Smoking Peanut," he has an Australian accent.
The shorts that Sandals wears are similar to Patrick's shorts since they both have Hawaiian flowers on them. The only difference is the size and color. They are the same shorts as the ones that Medley Fishbowl wears.
