Yumi Goes Solo:
Yumi has a dream of what it would be like if she went solo. She dreams that she had a huge mansion with her own robotic butler. She wonders where Ami and Kaz are. She finds Kaz making a catfood commercial with Jang Keng and Tekirai but the cats won't do as he says. She finds Ami playing the accordion, really badly, & asks if she knows who she is. Ami doesn't know Yumi. Yumi gets lonely and wakes up to find that it was all a dream...or so she thought she woke up completly. She wakes up to find that the cats have locked Kaz, Ami, and Yumi in a birdcage. She wakes up and feels glad that she is part of Puffy.
