using colonist to surround the Muffulo and heard into an enclosed area. they need to be fed and are not immune to becoming psyco. would be a massive burden on early game food supplies, but can be killed for food and you need at least 1 male and 1 female, and you can breed and make more! or maybe a more humane existence and make Muffulo ride able for a way to haul more supplies faster?
would work the same as a growing area, and must be placed on grass (would take up a lot of space)
