They are usually seen in the beginning of each episode, playing with their toys in the playroom. After they leave the room, the toys come to life to have an adventure, usually inspired by the children's games. Penny and Simon own almost the exact same toys as Jesse and Jamie in The Christmas Toy, including Rugby Tiger, Ditz, Balthazar (a slightly different teddy bear, but with the same name and voice) and Mew, who used to belong to the cat. The audience never got to see the children's faces.
