WeeWorld is one of the best and safest cartoonizers online. Easily cartoon yourself with just a few clicks. This is a really simple interface that produces a decent looking avatar. Not only can you quickly design and save your cartoon image, you can also interact with other “WeeMees” in WeeWorld!
This site offers a ton of games, forums, and social networking. No download required to create a custom cartoon. I like this site, check it out!
