When the weird robot attacks Bogey's Café, defeat it then the blue-haired person. When Harry asks if you are going home, tell him that you will wander around. Then go to Hero's home talk to Lucy (the woman that sweeps with the broom), You will tell her about Z, and she will think that it is a band and that you were a security guard. Talk about the band. She used to hear the Groovy Goombas and their hit song "Fire Flower Sunshine".
