Tambourine Dancer is a dancing, musical doll sold by Magnificent Reach. The name of the doll is Anita, and it appears to be from around 2001. The doll requires three AA batteries.
Another version of it was sold by Takmay Toys.
She has blue eyes, pink lipstick, her blonde hair tied up in a bun, and she wears a necklace with either a green, red, yellow, translucent star pendant. She also holds a tambourine in her right hand and stands on a blue stage that has star-shaped lights.
The Takmay Toys version appears to have smaller eyes that are painted on in a different style, and is only known to have a red pendant.
The doll can come with a white dress that's mostly decorated with yellow, pink, and orange roses, or another white dress that has pink, blue, green, and orange stripes and flowers.
I don't have a video which shows how it dances, but the doll probably shakes its hips while playing a copyrighted song.
