Mama Moon turns up at the McGuffles with a box of old toys of her daughter. Since the nanny is shopping, Mama Moon asks Luke and Lola to take care not to look inside. Of course, the curious kids do not stick to it. They discover in the box a game called "Magipoly" and want to play it. But as soon as they have taken off the lid, they are sucked into the game. Miss Moon is just coming home at the moment and just manages to get away with Luke in the game, because if you do not find the right shoot, you stay trapped in the game for ten years.

Yasir gives the children a poster of their family tree and asks them to take the baroness with her and hand her over. Unfortunately, Baby Joe drips some applesauce on it, directly onto the image of Sophie, the Baroness' oldest ancestor. The attempt of Miss Moon to wipe the muss only worsens the situation: she wipes the whole picture away. The result: the entire family branch of the Baroness disappears from the poster, including their house next door, as if it had never existed. How do they just bring their neighbor back?
