@paulp The problem is that the bone TurtleHead has Inherit Scale disabled, but the Unity Transform hierarchy, which mirrors your bone structure using SkeletonUtilityBone GameObjects, has no option to ignore parent scale.
The solution is to move the TurtleHead GameObejct from being a child of the Turtle4 GameObject (its parent bone) to being a child of the main SkeletonAnimation GameObject as shown below. Then remove the SkeletonUtilityBone component at the re-parented TurtleHead GameObject and instead add a BoneFollower component set to follow the TurtleHead bone.
Sorry that the setup procedure is a bit more complex here, unfortunately Spine's hierarchy system is more powerful than what game engines usually have to offer.
