I can't believe this movie hasn't been made yet. If I had access to my own movie set and 80 tonnes of marshmallows I would make it myself, but unfortunately I am lacking both of those things :(
on another note, did you know that marshmallows are called marshmallows because they were originally made from the marshmallow plant? I just found that out, and will probably immediately forget it.
anyway... have a wonderful day, keep smiling, hug everyone you see, and don't skimp on the high-fives.
