Rikki, Baxter, Yates and the Other Castle Kids are the children of the castle servants. They are spunky and adventurous and highly competetive with one another. Consider casting younger or smaller children so they don't appear physically threatening to Jack and Annie. The Castle Kids do not need to sing, so these are good roles for kids who are getting involved in theatre for the first time. Yates should be the strongest actor of the bunch as he is the one who stirs the pot and gets all of the other kids riled up.
