In "Peter and Lotta's Christmas", we meet Aunt Green, Aunt Brown, and Aunt Purple, their neighbor Uncle Blue, and the orphaned children Peter and Lotta, who have been taken in by the aunts.
Peter and Lotta experience for the first time how the aunts prepare everything for Christmas, and finally the day arrives and the 'Christmas goat' brings the Christmas presents. Peter and Lotta immediately decide to make something for the aunts and for Uncle Blue next year. But how can they find the 'Christmas goat' to ensure it delivers their presents? And who is the 'Christmas goat' anyway? When Aunt Purple tells them that the 'Christmas goat' is actually an enchanted prince who lives deep in the forest, their decision is made. They are going to look for the enchanted prince. When they eventually meet a charcoal burner in the middle of the forest in autumn, they ask him if he would deliver the presents to the aunts. And so, it becomes an extra surprising Christmas for everyone.
