How to catch Thorny Oyster
Use the Shellfish Tongs. The exact approach depends on the creature’s category and, for shore-dwellers, its species type.
- Equip the Shellfish Tongs and search the intertidal zone along the beach.
- Shellfish are mostly stationary. The Pearl Oyster is the notable exception and can move.
First catch: the creature is added to the Omnidex. Offer it to Mors at the Omni-Gallery to put it on display and unlock its Omnipedia entry.

The thorny oyster appeared on dining tables as a delicacy long before hamburgers.
It doesn't require complex preparation.
Simple seasoning is enough to bring out its irresistible, savory taste. However, note that during certain period, toxins can accumulate in the shellfish and potentially poison their consumer. Therefore, one should pay attention to the seasons when eating this delicacy.
