Poowas an undercover terrorist that joined The Starmen Company while he was undercover. Legend says that one day, we will attempt to destroy THE ENTIRE WORLD. Although, there currently wasn't any proof that he is still building up to that idea. It is most likely he was unemployed from terrorism. He could usually be found trying to suck Giygas' power into some plastic bottle, although he usually fails at doing this and gets his ass wooped. He is also said to be best friends with Ness and Lucas, although probably not, because numerous times, he was seen trying to steal their wallets.
He was named Poo because he was known for walking around doing poos.
