Yoko wears what appears to be a black jumpsuit. She is also seen wearing semi-transparent sun glasses. She has short, spiky, black hair, and a strangely shaped nose.
She seems to get angry easily, in "World Wide Recorder Concert" she became angry over the fact that four million 3rd graders did not know the song they were supposed to be playing (something that, due to their age, isn't their fault).
- In reality, Yoko Ono is much older than she was shown, she is currently 83, which would have made her 66 when this episode aired.
