Generally speaking, Morgana's puppets and dolls go on a scale of combat to non combat. There are exceptions, but those are unique.
For the humanoid scale, it goes like this:
On the fully combative side, there's the puppets that Aranwen has seen - proportions are outside that expected of humanoid, generally longer and thinner arms, magically reinforced in strength and durability, and its movements are incredibly shifty and jerky; no effort is made to conceal its nature, aside wearing a cloak or other loose clothing about it. Let's call these the alpha puppets.
Midway between combat and noncombat is the puppet Ch'dau and Kithran just fought - proportions match any of the races, depending on the specific puppet design. More likely to be overlooked in a crowd because the shape is right, and it generally moves in the right way, but it is still ball-jointed and can move in unusual ways. Sometimes she reinforces the deception with an illusion, to better disguise this kind of puppet in a crowd, ie disguise self type effect, but usually she just has them with cloaks or other loose clothing. Let's call these the beta puppets.
Finally, there's the noncombative dolls - they blend in extremely easily with people, aside the aforementioned traits - dull/distant eyes, always with a gemstone at their forehead, typically disguised by jewelry, and colder temperature than normal. Morgana often hides their eyes in some way. These are her crystal dolls. She does not have many of them.
Morgana does have and play with smaller felt dolls, usually for her own amusement.
