My little Hasbro Pokemon plush collection that I've had since I was 8, I think. I'm not even crazy about two of the Pokemon, but I just love them so much.
Oh, and my Leopard family, too. I've had those even longer, and the "mother" of the family has an interesting story. You see, I lost her. She was super special to me, and somehow, I lost her. A few years later, someone informed me that possessions of mine had been mysteriously dumped someplace, but that was all I heard. However, I heard descriptions of a few items, and it sounded like the leopard mother was among them. I wasn't able to retrieve anything. I lost a lot of my childhood things.
This happened about three, maybe three and a half, years ago.
Get this: I found the leopard mom two weeks ago, just before I got really sick. She was on Ebay. And how I know it was the same leopard - I had her marked very specifically, and some of her whiskers had been cut. Still, I wasn't 100% sure, but I rushed to buy her, and when she arrived in the mail, I got to examine her, and wouldn't you know it? A piece of my childhood came back to me!
Now she's crouching in her rightful place among her kittens and my Pokemon collection. <3
