From Creatures Wikia
The Angry Ettins are not a happy, pleasant breed. They hit Norns. They hit grendels. They hit the Hand. They even hit other ettins. They'll just stand and slap each other to death if you don't keep tabs on them.
They are very red and keep their color all of their lives. They are a mixture of many species, including most of the infamous killer Norns, Plague Ettins, Aggressive-tribe Ettins and Revenge Ettins, etc. The download now includes the egg file and a starter pair. The starter pair are babies in the download, but they know their vocabulary and have been taught to use elevators, vendors, etc.
