This toy is mainly characterized by intrigue. It consists of a surprise egg, made up of layers that a child can unwrap. Inside the egg you discover a secret message that provides you with clues about the doll's club, some stickers, a feeding bottle, shoes, clothes, a surprise accessory and, lastly, the toy inside a golden ball. These dolls have awakened a fan phenomenon that has not been seen in many years in this year’s letters to Santa. They are different from each other, so much so that, in addition to different existing models, inside each surprise ball you can find either a doll that cries, one that spits, and even one that goes to the bathroom. They are even organized by families, collectible and there are different releases - Series 1 and Series 2 -, which make them the object of desire for many little ones.
