http://www.technosphere.game-host.org/index.htmSomeone posted the link to this a fews years ago I think. I had made some creatures there, but I forgot all about it. I think the site must have went down or something. I just got an email about my account. Sadly all my creatures were dead. But I think I might make a few more.
This isn't like neopets at all. Basically you just make the creature then it does it's own thing.
