The Oyster is a grab bag-type item that always drops a Shucked Oyster, and has a 20*1/5 (20%) chance to drop (in order of increasing rarity) a White, Black, or Pink Pearl. It is acquired by fishing in the Desert biome. The Desert biome must not overlap with the Hallow.

Tips

• As with other types of grab bags, it is always worthwhile to open Oysters. Along with the edible Shucked Oyster, which can be sold for 20, the pearls will sell for, on average, 5111 per Oyster on the  Desktop version, or 5456 per Oyster on the  Console,  Mobile, and  Switch versions.
• Crate potions increase your chance of fishing up an oyster. (Verify)
