Goats are NPCs in Goat Simulator. All goats (except for Pilgor) will stand still without moving, except the goats in the goat fighting ring and the ones in Goat Castle, even though they only bow when Pilgor walks by.
If the player baas at a goat, it will baa back.
Three other goats share Pilgor's pen in Goat Ville. It is possible to lick/headbutt them.
