A pack

A Pack is a mechanic in the Creature Stage which allows the player to add a group of creatures in their pack, including, but is not limited to player's own species. The members of player's pack will follow and help to kill or socialize with other creatures. It can hold up to 3 pack members. In order to add a creature to your pack, the creature must be an ally or of the same species as your own. Player must then socialize with this creature, and it'll join your pack as long the pack doesn't already hold the maximum number of pack members.
