Transforming Creeper Flicker (no music)

[Intermediate] How to fold a Creeper Flicker that flicks like a ninja star or like a boomerang and it’s mouth can slide open huge and close shut. The whole model can transform into a “The Creeper Scream“ a take-off on the painting “The Scream.“ (See 14:49 for explanation). Another special feature... notice that in the square flicker position, there are no folds inside the eyes or mouth. From a design standpoint, that was not easy to achieve, but I think it makes the model look a lot cleaner than my origin
