King Oyster guide

King Oyster is a Rare catch tied to Terrapin Island, and its description is specific: it is a special breed of oyster found only around that island. It shows up at any hour and in any weather, but only in Summer or Autumn. No bait is listed for it.

It is very light. The average weight is 0.6 kg and the max is 1.7 kg, which ranks 607th of 663. The per-kg price helps: C$200 per kg gives an average catch of C$120, which ranks 568th of 742 documented fish. Base XP is 35, low for a Rare, so it does not do much for levelling.

Two rods are sold on the island, the Magnet Rod and the Wildflower Rod. Between them, you can gear up while you wait for the right season. The honest assessment is that King Oyster is a seasonal curiosity: worth picking up when it appears because the conditions are so open, but not worth planning around given its modest value and XP.
