How do I get the key to open the locked door in Flopside?

Go to the house with a cyrstal ball on it in flopside, then jump behind the person and talk to her. You HAVE to jump behind her before talking to her or she'll just offer you a charm. This will send you on a quest through the first chapter, flipside and flopside. When you finnally get the key use it on the door to get piccolo. Also, you can get any charm for free. I reccommend the speacial package.

Here are the steps to follow. There are a lot!

1. After completing chapter 5-4 go to Merlee's house in Flopside and talk to her from the right side. She will ask you to go to Merluuve's house in Flipside to get her a crystal ball. Accept and go there.
2. Once you're at Merluuve's, talk to her. She will ask you to get a trainee's kit from Bestovious in chapter 1-1. Accept and go there.
3. Once you're at Bestovious's, talk to him. He will ask you to get the you know what from old man Wachitt in chapter 1-2. Accept and go there.
4. Once you're at Wachitt's, talk to him. He will ask you to get a signature from Merlumina in chapter 1-4. Accept and go there.
5. Once you're at the end of chapter 1-4, Merlumina will appear. She will talk heaps. Just skip the boring dialog. Then she will sigh the paper. Go back to Wachitt.
6. Once you're back, talk to Wachitt. He will give you the you know what. Go back to Bestovious.
7. Once you're back, talk to Bestovious. He will give you the trainee's kit. Go back to Merluuve.
8. Once you're back, talk to Merluuve. She will give you the crystal ball. Go back to Merlee.
9. Once you're back, talk to Merlee. She will give you an old key and a free charm.
10. Go to the locked house and unlock it. Inside is a chest and in the chest is Piccolo.
