The outline includes all the parts of the puppet which are on the same mesh and move/warp together. This may be ok, depending on how you want the puppet to move, but if it isn't, you can change it by toggling the crown icon for the group (like the eyebrows and pupils which are currently marked as warp independent so they move separately which is generally what you want). Note that if you make the parts independent, you may have to adjust how they are attached to each other so they don't pull apart in ways that you do not want.
