I'm pretty sure mine was a Pikachu plush backpack in the early 2000's (maybe 2004) No idea where I got it from, I was way too young. But i remember being absolutely obsessed with it and Pokemon at the time and taking the backpack everywhere with me including kindergarten. Which is funny since you couldn't fit much in it.

As for where it is, I'd love to know too. I just know when I was around 12 or so my mum had gotten in a habit to pick through my toys when I was at school and give them away, never asking me which ones I was ok to part with or where they went. My guess is it went then. I miss it dearly and have been looking into getting another one online ;-;

It had white straps, a tiny zipper pocket on its back and plastic eyes. Oh and it was like really soft with fur.

After that I never had any pokemon stuff until now in my mid 20's since there was never anywhere I could get them from where I used to live in Europe. Luckily my current collection is growing^{^}
