Common features of a Doll Dancing Princess toy include:

Dancing/Spinning Motion: The doll is built with a motorized base that allows it to spin, twirl, and "dance" on a flat surface. Many have a "bump-and-go" feature, where they automatically change direction when they hit an obstacle.

Lights and Music: The toy's dress, crown, or other parts often light up with colorful, 3D LED effects. It also plays a musical melody or song while dancing, creating a magical atmosphere.

Princess/Fairy Design: They are usually dressed in a beautiful, flowing gown, often with wings or a blossoming skirt that opens as the doll spins, resembling a fairy or a royal princess.

Interactive Play: These toys are designed to encourage children to dance and play along, helping with their motor skills and sensory development.
