I was thinking of a Vampire Flytrap. With a giant black cape on it, complete with a white shirt. And, have the flytraps teeth shaped like fangs at the top; maybe the bottom row of teeth too. Complete with a red crimson bow.
It could be shaped like the Flytraps in Dresses too, so that way the size reference is already there. Take for example; the Bride Flytrap. It has a parting for the wedding dress. The Vampire Flytrap could have a parting too. The black cape could be the first half, and then the last half be a white shirt. The parting could happen where the first parting is at on the Bride Flytrap.
(Or even like the Caroling Flytrap, for reference)
Now thinking about it, I really hope this Vampire Flytrap comes to be one day.
