I used to play an online game when I was little that I wanted to check out again to see if it still existed.
I don't remember too much but it was pretty popular around 2010 (in Sweden at least) and I'm pretty sure you were a panda that you could customize and from what I can remember you could also change the color of your panda (like yellow and white, or pink and white etc.) But I could be wrong and you could only be blank and white, I'm not entirely sure. I think there were missions you could do as well and you could also talk to other players.
That's pretty much what I can remember about it, so if someone think they know the name of this game then please tell me!
