I used to love Dolly Surprise. She used to have her hair tied back into a pony tail and when you moved her right arm up to the butterfly clip her hair used to grow really long. I remember spending ages brushing and combing it. Then, when I got bored of it being long, I just used to move the same arm backwards and forwards and the hair used to go short again. I loved Dolly Surprise, it kept me entertained for hours!
