Asspider vs. insecticide

This is kinda old, but I like it. It's a short story about a boy with an insecticide can killing spiders and The Asspider finding a solution to revenge her friends. The animation and drawns are not so good for it was made in a day or two, if I remember well.
Asspider is a spider who can't do webs, so she tries and farts a lot trying.
