This is the Echo Base litter box built by writer Mike Ryan. Because what better way to tie your Star Wars toy collection together than with a place for cats to shit? Nice collection, Mike, but it smells like a wampa's @$$hole over here. One time I went to dinner at a friend's house and they had their cat's litter box in the kitchen and that's when I called them both disgusting human beings and told them I'm not risking getting worms for some half-assed spaghetti and meatballs.
Thanks to JN, who wants a Jabba's palace litterbox and doesn't even have any cats.
