old childrens mmos

i love old children's mmos. club penguin was my favourite, but only because that's the one my parents bought me a membership for, lol. in hindsight, my favourite has to be fantage. i absolutely LOVE its aesthetic, it's just so nostalgic. also does anyone remember that build a bear one? i forget the name but i have fond memories of it, even if they're a little vague.
