When they wish they could visit a real castle someday, then Barney comes to life and he takes them to an echanted forest. They meet a royal guard named Elijah the Royal Guard who likes to play games make new friends. He takes them to the next hill where the castle is at. Then, Elijah magically disappeared. Kathy, Carlos, Shawn and Tosha ride on pretend horses for three times around the castle. The castle gate just opened at 12:30 p.m. in the afternoon. At the castle, they meet the king, they wore castle clothes, had a royal tea party with BJ and pretend to be the Royal musicians to be performing a song for Barney and BJ. They went back to Carlos' backyard.
