Even though it's a very weak Pokemon, I actually kinda like Ariados. I remember using one when I was replaying one of the Gen 2 games. The title comes from the fact that Spinarak and Ariados are the only Bug-type Pokemon that can learn Night Shade (according to Bulbapedia). I was on a Pokemon drawing binge and this guy was requested by  khalrin.
