Shell

Shells are plentiful items that wash up on the ocean shoreline of all four games. They are an easy, yet small, source of Bells, and are especially useful the first few days to obtain enough Bells to buy tools, such as the fishing rod or net.

Shell Prices and Game Availability
Prices and availability of shells are the same in Wild World and City Folk.

In Wild World
Scallops can be traded in the Golden Axe Trading Event to obtain the Golden Axe or Pascal's Pic. They can be obtained from Tortimer in exchange for a massage chair.

In City Folk
Scallops can be traded with Pascal for a piece of ship-themed furniture.

In New Leaf
Scallops are now found by diving, instead of being found on the beach, and are now a type of deep sea creature. Upon being donated to the Museum, it can be found jumping around in the large tank in the first room of the ocean exhibit. The exhibit says this about the Scallop:

"Scallops inhabit the cool ocean bed. They swim by rapidly clapping together their shell valves. The black dots on scallops, known as wavy "strings", are actually their eyes. These eyes number over 80 but only really function as a means to sense light rather than motion. Often grilled or buttered, scallops have become a tasty seafood enjoyed all over the world."

When a Scallop is found by the player, Pascal will rise up from the surface and ask the player if he can have it. If the player chooses to give it to him, he will give the player some furniture in return.

In New Leaf
Pearl oysters are also now found by diving, instead of being found on the beach, and are now a type of deep sea creature. Upon being donated to the Museum, it can be found sitting in the large tank in the first room of the ocean exhibit. The exhibit says this about the Pearl Oyster:

"Pearls are formed when mostly calcium carbonate and protein envelop foreign substances. Pearl oysters have numerous threadlike feet sticking out from their shell opening. These allow them to latch onto surrounding rocks and are actually surprisingly strong. Their adductor muscles are edible and are considered a delicious ingredient in some foods."
