The Cthulhu is a Pet.

Taking care of the onboard Pets is the next level of things to keep the crew busy when it is not too busy.


The Cthulhu possesses an octopus-like head whose face is a mass of feelers, though its body is of a dragon with a pair of wings and a tail. This is the only Pet that floats by flapping its wings instead of undulating along the ground like other Pets' sluggish movement.

For Halloween, it holds a Jack-o'-Lantern Trick-or-Treat basket in its arm.

Unlike other Pets, the Cthulhu is mute, making no sounds whatsoever as it has no audio.


The Cthulhu has two inventory slots that can be accessed when alive and grabbed by the player. Any small items can be stored here, but mostly one of the slots is for the ID Card icon.png Pet Name Tag if the player wishes to name the Pet. If it dies, the body will splatter and any contents in its inventory will be destroyed.

It also has two kinds of hidden behaviors that the crew needs to pay attention to: Hunger and Happiness.


Every Pet needs to eat to relinquish their Hunger, which increases by 0.03% every second. At 30% Hunger, Pets become hungry and the Pet Hunger.png Hunger icon will appear above their head to notify the crew that they need feeding. The player can feed them by dropping an appropriate food item on the ground and the tamed Creature will approach and consume it immediately. It stops requiring food when Hunger is below 30%.

There are three Pet Food types that Pets can consume: type 1, type 2, and type 3. Like the Psilotoad, the Cthulhu can only eat Pet Food type 2. However, it satiates only 10% Hunger, but still increases 5% Happiness. Therefore, the Cthulhu requires a larger quantity of Food to fully sate its Hunger compared to other Pets.

Items that are classified as Pet Food type 2 include:


The Happiness is the state of Pets that ensures the occurrence of high quality item production.

The Cthulhu's Happiness decreases by 0.016% every second and can be increased by being fed or played with. There is a 6 second cooldown before the player can play with it again.

When Happiness is high enough and Hunger is below 30%, the Pet Positive.png Happy icon will appear above its head. But if Happiness is low enough regardless of Hunger rate, the Pet Negative.png Sad icon will appear instead.


When well-fed (0-30% Hunger), the Cthulhu will start producing some items, most commonly a pile of Poop.png Poop. At 80% Happiness and beyond, there is a 15% chance it will lay the Strange Egg Balloon.png Strange Egg, which can be deconstructed for materials or used to hatch another Cthulhu. Other than that, it has no other unique items to produce like other Pets.

All produced items are dropped on the ground from the respective Pets, which can be harvested simply by picking them up.


  • The Cthulhu is a reference to the short story The Call of Cthulhu created by American writer H. P. Lovecraft.
