Undefined as never said anything on the chat. Undfined will always attack anyone who pooed on him. His only enemies are nonames since he cannot see them and they can attack invisibly.
Tip: If you see Undefined and you are a bigger bird nesting, I would suggest leaving or changing into a Robin and then nest. I was a Macaw and once my egg hatched, it announced it on the chat and undefined immediately came and killed me. Most killers will go to Island 1 not Island 2. Island 2 is a good choice for a place to nest in. If you are a noname, try to kill undefined for a big challenge!
