A Mimikyu bobblehead statue!

Just super glue the PETG spring onto the top of the body and the inside of the head and you're good to go!

Design-wise I wanted to make it SLIGHTLY more “realistic" (for lack of a better term) with how the head's mouth is more an indentation instead of a zig-zag line all in black. The body is similarly designed, with the shape of the body trying to resemble cloth draped over something else and the little black parts of Mimikyu's true form just poking out more like toes rather than triangles.

The spring is relatively thin and just super-glued in so best not to be too hard with shaking it, but should hold together enough to wiggle around like Mimikyu's head tends to (especially after its Disguise ability is activated).
