This was a doll with long hair that moved by itself!
She would sit down with a white tray over her legs with her own little tea set. You put her teapot in one hand and a plate in the other.
On the tray their was a groove where her teacup would sit. I would put pop in the teapot and a biscuit on the plate, when she is switched on she would turn her body and pour pop in the cup on the tray, then turn her body the other way and offer you a biscuit.
