Tommy and Annika are on their way home from school and, as usual, they walk past Villa Villekulla. As usual, they say “I wish someone would move in there, someone with children”. Then, they suddenly see someone moving in the house – a cute little monkey! And there is a spotted horse on the porch, and inside the house, someone is sleeping with her feet on the pillow. From that day, nothing is the same for Tommy and Annika.
