The Glacier Ettin genetic breed was created by Avocado. Glacier ettins are genetically engineered to derive boredom from heat and sex drive from cold. They do not shiver from the cold.
Glacier ettins can breed at youth, and they age a little differently than normal ettins. They are prolific breeders, and can easily become too crowded and begin slapping each other to death.. They prefer toys and machinery, and seldom steal gadgets.
