The creators of Adventure Time have long been dreaming of the perfect video game adaptation for the series. So much so they're starting to write stuff down. And share it!
These sketches are the product of a little brainstorming session between Adventure Time creator Pendleton Ward and Patrick McHale, one of the show's writers.
I never thought I'd live to see the day I saw Animal Crossing, Mount & Blade and Ultima Underworld share a design document for a kids cartoon series, but I'm sure glad I did.
While we're on the subject, you can see some art for Ward's new series, Bravest Warriors, over on io9.
