Earthworm Jim...? "All of my Yes", as they say! Those games were quite underrated! This was one of the very, very VERY are anything's I felt ever got randomness done right. This and Alice in Wonderland!
And, if you're wondering who owns him... I wish I could figure it out, too. He was originally created by Shiny Entertainment. Looking though some history, here, he might currently belong to Interplay Entertainment, VIS Entertainment or Atari. I've narrowed it down that much!
God I miss that show! Nice work, you've made me instantly go searching for every episode I can find. Already have the games. But on an artistic level, this is such an awesome take on the character design. I would pay to see a new show/game in this kind of style.
