Giant Oyster

The Giant Oyster is a monthly Distraction and Diversion within the sunken Tutorial Island that is accessible upon completion of Beneath Cursed Tides. Players can collect and catch items to feed to the Giant Oyster, receiving Fishing and Farming experience from doing so. Once fed, the Giant Oyster will close its mouth, preventing further feedings. The following month after being fed, the Giant Oyster can be checked, opening to reveal treasure inside for the player to collect.

Players can leave the island by teleporting away or by leaving to the surface through the bubbles in the building north-east of the seaweed patch.

Free-to-play players may gain Fishing experience from fishing sea cucumber, but will not receive any rewards.

The Giant Oyster can be reset with a monthly D&D token.

Getting started

To begin feeding the Giant Oyster, speak to Wizard Myrtle, found in front of the entrance to Wizards' Tower. She will let you dive to Tutorial Island.

If the Oyster is already closed (from feeding the previous month) the player will not receive the sea cucumber or delicious seaweed items, but will still gain experience from the Fishing and Farming activity. If the player gains the maximum monthly experience from these activities without receiving the items, they must then loot the Oyster before re-attempting to fish and/or pick seaweed. Once the Oyster is open, they can then harvest the missing item(s), but will not receive any additional experience for the action. It is not known if this is a bug; however, there is no effect in terms of experience or rewards if the player forgets to loot the Oyster first and has to re-attempt the Farming or Fishing activity.

After feeding the Oyster the delicious seaweed and sea cucumber, the Oyster will close.

Feeding

The player must obtain a sea cucumber and delicious seaweed and feed these to the Oyster, which is found in the cooking area of Tutorial Island. Bonus experience is not gained when harvesting; experience-boosting sets will not boost experience gains either.

Sea cucumber

The Fishing spot

A sea cucumber can be fished from the fishing spots found west of the Giant Oyster. When attempting to fish, the player will gain Fishing experience 30 times before finally catching a sea cucumber. The amount of Fishing experience gained depends on the player's Fishing level.

The Fishing level can be boosted, and the player will receive the rate based of the boosted level (i.e. a boost from 94 to 99 will give 6,966 experience each harvest). As the boost wears away, the experience rate will as well.

The amount of Fishing experience gained from harvesting the cucumber is roughly three times of the amount of Farming experience gained from harvesting the delicious seaweed.

Delicious seaweed

The tasty looking seaweed patch

Delicious seaweed can be harvested from the tasty looking seaweed patch north of the Oyster, near the large Jellyfish. When attempting to harvest from the seaweed patch, the player will gain Farming experience 30 times before finally harvesting delicious seaweed. The amount of Farming experience gained depends on the player's Farming level.

The Farming level can be boosted, and the player will receive the rate based of the boosted level (i.e. a boost from 94 to 99 will give 2,322 experience each harvest). As the boost wears away, the experience rate will as well.

The amount of Farming experience gained from harvesting the seaweed is roughly one-third of the amount of Fishing experience gained from harvesting a sea cucumber.

Rewards

An example of the rewards obtained by looting the Oyster.

At the monthly reset, the closed Oyster can be opened. Looting the Oyster will reward the player with items from the Treasure Trail reward tables. The player's total level is used to determine which tables the player can roll on, such as easy/medium/hard, or hard/elite, and then chooses between them randomly. While the rewards mechanic is similar to completing a treasure trail, the rewards cannot be re-rolled like those from a treasure trail clue scroll. Unique treasure trail rewards from the Giant Oyster will count towards the Treasure Trail collection log.

Achievement

• Oyster Mash ( 5) - Feed the giant oyster on Tutorial Island.

Trivia

• On 11 January 2016, a bug allowed players to repeatedly reset the oyster. This was patched within the hour. Players who abused the bug were banned or rolled-back, based on how much they abused the glitch.
• On 11 April 2016, it was made possible to use the monthly D&D reset token for this D&D.
• It's highly recommended if intending on using a Luck of the Dwarves ring to loot the Oyster before looting the seaweed and fishing at the fishing spot. Leaving the underwater area and coming back will lock the Oyster chest until the next regardless of the next reset, even if you didn't get to loot it.
