My Size Barbie.

haha. Seriously. When I was 6 or 7, that was ALL I wanted for Christmas. I LOVED that thing. I don't think they make them anymore.
and Polly Pockets. <3 I played with those for hours. I'm pretty sure they put a recall on them because they were a choking hazard. and now they're big.
Then there's also Amazing Ally. But I didn't love her - I hated her. She was this doll that you would record your voice, and then when you talked to her she'd do stuff. I recorded when I had a cold, so then I couldn't use her once I got better.
