Shell City is the gift shop that held Neptune's Crown. As seen in The SpongeBob SquarePants Movie. The gift shop is owned by The Cyclops, who also works there. The gift shop contained 1,007 dead. SpongeBob and Patrick almost got turned into knick-knacks by the Cyclops there, but they eventually escaped Shell City with King Neptune's crown.
It is a live-action gift shop on an unidentified beach. It is fairly small wooden shack. The shop contains miscellaneous items, a glass bowl, but mostly knick-knacks (dried up marine animals)
