And Elliot has a hot dream of his new girlfriend, where he "catches" a scantily clad Mareep and just as she's about to evolve, he wakes up. Also, he's subconsciously changed girl forms to either a female Pokemon trainer or a female shepherd. Hilarity by Ellen ensues.
much as I am saddened to not see further evolutionary lines of the Ashleep(c'mon, its the best I can do for poke-names), I would however like to mention that nudity is actually pretty irrelevant on the further evolutionary lines since...well...seriously, artistic license! You don't have to do that, just make it designed close enough and people will get it.
