Tamed Lymantrias make excellent base buddies. They are slow and agile - making them ideal for offloading dinos and building tall bases. They can also easily land on a target 1x1 square, and usually stay on that square if you need to turn while landed. This particularly is useful for reloading turrets or placing that last ceiling. For low level base buddies, level weight and stamina. For high level base buddies, only level weight.
