What is the little doll on top of Tomoko's phone? In WataMote, Tomoko's phone appears to have a little figure on the top of it. It looks like a doll, with a kitty-face smile and an orange coat and antenna. In the ED sequence, it appears again, in both orange and blue.




Is this doll a reference to another series or Japanese pop culture? What does it mean?
That guy is apparently from the Wii game Opoona where you play a character called "Opoona" that's short and has a number of facial expressions (and one of them has a ball over their head), though they don't always have such a sour look on their faces.





Some ascii art of Opoona with the Yaruo face that Krazer mentioned:
