Shell (Cozy Grove)

Shells are natural resources found on the shoreline in Cozy Grove. The player can pick them up at any time and they appear multiple times a day. The available shells vary by season and each shell has a type and an attribute which define its rarity. A maximum of 20 shells can spawn on the island per day; once the player picks all twenty, the shells stop spawning until the day changes.

Shells are one of the categories of items requested by Captain Billweather Snout for the collection. Shells can also be sold to shops or used to craft models at Octavia's Shell Models.

All shells stack to 30 in the player's backpack or storage.

Classification

Type

There are seven different types of shells: clams, conches, cowries, corals, snails, stars, and whelks. However, each shell has a specific name, which may or may not refer to its type.

A clam

A cowrie

A conch

A coral

A snail

A star

A whelk

Rarity and Appearance

Each type of shell has five degrees of rarity. Their appearance changes as they become rarer. Common shells are called rough, uncommon ones smooth, rare ones sparkling, legendary ones glowing, and mythical ones crystal.
