This is how you do it!
1: Get a pink wig, ears, white panties, a tail, and pink stockings
2: Find a dressmaker who can do this, or you can. There should be an iron wire on the hem of the dress so it says in a circle space. The petticoat should be inside her dress.
3: Make a PikoPiko Hammer!
And there ya go! You are Amy!
