Shaco Skin

I think Shaco is a prime candidate for a Surprise Party Skin. While Fiddlesticks does his all at once, Shaco has that same kind of feel, but he can do it through invis back stabbing you, chasing you into either his clone or his boxes. When he comes out of invis, he can do a similar horn sound that Fiddle makes to create that same kind of panic.

Thoughts?
