Catcoon

The Catcoon is a animal in the Reign of Giants DLC. It will wander around, pouncing at trees and digging at various objects, sometimes destroying them. When it sees a small Bird, Rabbit, Moleworm, Butterfly, or Bee, it will pounce at it and kill it. Catcoons are hostile toward each other and will attack if they get too close. When killed, a Catcoon has a chance of dropping a Cat Cap.

Catcoons can be befriended by giving them food or "toys", and will give "gifts" to the player by coughing up items such as rot and grass as if a hairball. Each item given to the Catcoon will add a third of a day (160 sec) to the time they spend following you (up to a maximum of 2.5 days ) and halve the time between hairballs. The item that they give depends on the number of times they hack before coughing it up. Currently there are two lists for neutral and friendly hairballs, but at the moment they are identical.

Things they will attack or eat:

Bugs

 * In the current patch, "A Feet of Strength" (And apparently also Giant Steps), if given food when in a jump or vomiting animation, the Catcoon will eat it and then sit still forever. Can be fixed by relaunching the game.

Trivia

 * Catcoon is a portmanteau of "Cat" and "Raccoon".
 * Catcoons spawning a total of 9 times is a reference to the belief that cats have 9 lives.
