Pack

Pack
The pack is a group where you're the leader, present in creature stage. The members of the pack will follow you and help you to defeat or charm with other creatures, being very useful. It can hold 3 allies (of your same species or not) and more you, the leader of the pack. To add a creature to your pack, the creature must be an ally or of the same species. You must charm then with this creature and it will join your pack if the pack doesn't already holds the maximum capacity.

Rogue creatures
Since as rogue creatures are not enemies as epic, you may charm with them, ally with them and finally charm then again to add them in your pack. Rogue's are so useful in packs as they always have all abilitys of socializing and attacking; and as them have 250 of health, which may help you a lot in killing any other creatures, principally epics. But to pack them you must have high socializing abilitys and one pack member left, so it won't be easy, since this left pack member could help you. To socialize them easier just do this:

-Have your pack full

-Find the Rogue and charm him

-Still with a full pack, ally him

-Fire the last of your pack members and then pack the rogue

It isn't 100% working, but it makes it easier. After lots of tries, it's better to give up and kill the rogue... Remember that more than one rogue can be found in the whole world, so after you've packed the first, it'll be easier to pack the second and the third, as your pack will become more powerful.

Reference to pack in other stages
The one-eyed fat creature (that looks like Mike, from Monsters A.S.) that appears in the space-left pack members also appears in other stages and situations, as it looks to representate the creatures in the whole game.

Tribal stage
In the tribal stage, when you have a space left for another tribesmen, Mike will be in this space.

Space stage
Mike appears when you have space left for allies (even if they are ships not one-eyed fat creatures) and in ship utilities related to creatures symbol's, like in Wildlife Sanctuary and many others

In space stage there is a pack-like thing: the allies, that have about the same use as the pack in creature stage, except by the fact that you cannot add an own empire ship to your allies, and there aren't any epic or rogue ships...
