About unlocking piccolo: flopside merlee asks you to retrieve her crystal ball from flopside merlee who then asks for her training machine from bestovious. You go through chapter 1-1 to get to him. Then he wants you to get the "you know what" from old man watchitt (aka mayor of yold town) in chapter 1-2. Old man watchitt wants you to get an autograph from merlumina in chapter 1-3. Merlumina blathers on incessantly before finally giving you the autograph. Use the return pipe to exit and go to chap. 1-2 to old man watchitt. He gives you the "you know what." use the return pipe to exit and go to chap. 1-1 to bestovious. He gives you the training machine. Use return pipe and go to flopside merlee. Give her the training machine. She gives you a crystal ball which you take to flopside merlee. Then she gives you a random house key. The locked door is on level 3 on the other side. If you've finished the game, it should be the only locked door (I think). Unlock door. Go to chest, open, there's piccolo.
