The clones Little Otis and Little Abby come back to visit the barnyard, but it becomes a problem because they never sleep so the animals couldn't sleep when they're here. In order to make them stop visiting, they try to create mini-clones of more animals so Little Otis and Little Abby can have friends. But things go awry when the owner of the Clone-a-torium plans to use those clones to expose the humans so they would know that animals can talk, and Otis and his friends must stop him from doing it.
