There are now only five "Dolly Knows" dolls left. They were made in 1962 and would say "Yes," "No," or "Maybe." when you pulled a string. They were suppose to be like a magic 8 ball you can cuddle. They turned out to be too creepy and the line was discontinued. Most of the dolls were melted down. There are now only five. They will still answer your questions. All of them.
This was something you needed to know.
