This was a result of just having some fun. :3 You don't see very much fanart for Lord Slug out there. The fruity background was taken from a still of the film -- its of that weird, terraform-ready spaceship he lands down in.
(I'd also like to mention i'm hurting for money, so if someone wants to buy the original of this and has a good offer, I'd be happy to ship it off to you.)
