This irrational fears of spiders. :) Or other insects, for that matter... it makes for some interesting cartoons! And I really wasn't expecting this one. Really, really, unexpected! XD Even saying so probably won't lead others to expect anything of what this has to offer. I do love a surprise.
Particularly well-animated too, and the sound-design in particular. It stops and flows with the animation, but also carries with it a whole heap of atmosphere and intriguing eeriness. Awesome work with this!
