Mabel, Pacifica, Wendy or an unknown character... Who represent the llama in Bill Cipher's wheel ?

The only llama we saw in the show, was on a Mabel sweater, but it isn't the same. In my opinion, I don't really see the interest of two symbols for Mabel (Shooting star). Then, there is Pacifica, actually, I would never thought of her before seeing theories, and... Why not, after all, she's concerned by the mystery of Gravity falls and, to my mind, she has the same level as Robbie (who is in the wheel) in terms of presence / utility. The only problem for me is... Why a Llama ?

Now, Wendy. Honestly, I would like it be her, but I have quite a few doubts,because of the ice symbol. See theories about the wheel
