With a cheerful and somewhat naive personality, Emu is highly impulsive, acting on every idea that he comes up with, with a tendency to drag people around into his plans. Emu has established his own personal catchphrase, "Wonderhoy!☆" which he uses as a way to motivate himself and others. [citation needed] Though he is often in a joyful mood, Emu often neglects his more negative feelings, putting on a smile as to not worry those around him.
