Trade with Shrunken-Littlebro

At an MLP con, Cody Williams met a man, a most interesting man. This man said he had a way to transport someone to the world of his dreams. In Cody's case, this world is Equestria, and he, with only a slight reluctance, decides to hop through the gate, and arrives on Sweet Apple Acres, a dream of many of his peers. Of course, most of them dream of being there and being slightly larger than a field mouse. Oops.
