The Classics - Trudi's Heart. The protagonists of this world are depicted in plush families, where the smallest stuffed animals are, just like in reality, as small as baby animals. As they "grow older," the stuffed animals naturally become larger as well. Each of the Trudi plush toys is carefully designed and built to last a lifetime. Only high-quality fabrics are used in their production. The stuffed animals are machine washable. These cuddly friends are specifically made for children to help develop their sensory and psychomotor skills.
