When wild they are a pest, they steal your stuff and murder your tames.
But when tamed, they are amazing, have a pego, set it on somebody, it will then steal whatever is in their last hotbar slot, if they have nothing it will take a random item.
Better still, tame a whole army, they will Rob your victim of literally everything, berry seeds, superior kibble, guns, broken pickaxes, cryopodded pets, saddles, life, their job. . .
Nothing is safe from a pego army. . .
