Add some particle effects when Earworm changes size in boss battle

[melanie]

In the boss battle scene, the Earworm gets smaller every time you finish an instrument family. However, he just abruptly changes his sprite, so it's not super-clear that it's happened (especially since it's during dialog).

It would be very cool if there was some sort of graphic "poof" effect before the sprite changes - maybe it can be done in the same way as the fairy's particles-while-speaking, or maybe it just needs to be worked into the animation itself somehow?
