What are those wierd doll things that appear during the cartoon network commercials?

You know, those white doll things with no faces that appear during the commercials on cartoon network and they change colors and most of the time they are look alikes of the cartoon network characters.

Just watch cartoon network and wait for a commercial break and you will know what im talking about.

Seriously what the hell are those things? I've been wondering that for awhile but I kept forgetting to ask the question on Yahoo Answers.

they're just for entertainment... they are freaky though!

oh they seem to be just icons, they change colors or tell u what just ended and what's about to begi or just to be funny, i like them lol
