Harry Bauer, who over the summer mashed up Arnold Lobel's beloved children's book characters with the Dark Knight and his arch-nemesis best buddy for Batman and Joker Are Friends, has returned with another video called Batman and Joker Are Friends -- Down the Hill.

Based on one of the stories from the 1976 book Frog and Toad All Year, it features Bauer's drawings and voice work over Lobell's figures and story as The Joker convinces a melancholy Batman to venture out into the snow to go sledding. The Penguin even makes a cameo as Batman discovers that, yes, winter is fun.
