Gorilla

Gorillas are sanctuary animals. They are unlocked at reputation level 9.
Like all other sanctuary animals, players can only have four of them, one of each type.

Appearance
Gorillas have two different adult appearances: silverback and black, and two baby appearances: grey and black.

Silverback
Black
Grey Baby
Black Baby

Unlocking gorillas
Unlike other animals, gorillas cannot be bought. Players must unlock them by finding puzzle pieces (which are collected in a log book). 36 pieces are required for each animal.

Once players have obtained the first adult gorilla, the puzzle for the other adult gorilla is unlocked, and so on for baby gorillas.

Placing gorillas
Players must pick up a gorilla house to be able to place the animal in the sanctuary. The house is free and can be obtained from the Shop.

When the second puzzle is completed, players are asked to upgrade the house, which does not cost anything. The same happens when players complete the baby gorillas puzzle. When the house is big enough to welcome a new animal, it is delivered in a crate, "airlifted" into the sanctuary by balloons.

Feeding gorillas
Gorillas, like other sanctuary animals, can be fed with wheat bundles. Once gorillas have eaten they roam the sanctuary for ten hours and finally fall asleep. Players can immediately wake them up to receive 25 xp per animal and a chance to get supplies. They stay asleep otherwise.

Gorillas which have been woken up but are not fed for a long while cannot fall asleep and wander around looking sleepy and tired.

Tip: Waking up sanctuary animals one by one instead of using a whistle can increase your chance of getting supplies.

Decorations
Each gorilla unlocks some decorations in the shop as specified below:

Bitter Aloe (Silverback)
African Violet (Silverback)
African Lilly (Brown)
Pincushion Protea (Brown)
Badminton Ball Tree (Grey Baby)
Snake Plant (Brown Baby)

With each animal players are given the first pair of decorations for free. They are unlocked in the Shop when you get the first animal.
