Shell

Shells are common items that wash up on the sea shoreline in every Animal Crossing game. They provide an easy, yet minimal, source of income, and are often used in the first few days in order to obtain enough Bells to buy tools. A limited number of shells appear at a time, usually 15.

If they are picked up, they will slowly start to reappear in a new location. Dropped shells do not affect the player's environment rating. Entering buildings and saving the game will likely cause new shells to show up. Coconuts that wash up on the beach in and  do not count towards the 15 shell limit.
