Cathy had a thought that she would find his home; his palace... When she glanced at her apprentice, she was sitting next to a girl. But when the other girl sat her feet turned into a mermaid tail. She saw it and got an idea, she rushed down to talk to her. With Ducky and Nat, "Hey... I actually... Love you"Nat answered, then Ducky smiled and she kissed her on her forehead. Then, Ducky asked her if they could kiss, and Nat accepted it. When they were nearing to touch each other's lips, Cathy showed up! "Gah!"the two screamed, "Ducky... Can you turn me into a mermaid?"she asked, "What brought this up?"Nat asked as she replied "Just please, help me... This is very important"she pleaded. "Okay, I will help you dear Princess"Ducky replied with a smile as she lead Nat and Princess Cathy to her home where she and her mother lives(homes under the castle). She gave Cathy a magical light blue oval shaped crystal, "Here, dont loose it. Keep this crystal intouch with you, if this fell into the wrong hands. Everything would go wrong, also in order to turn into a mermaid. Control your thoughts"she said as Cathy rushed up to her bedroom and made a necklace with the mermaid scale on the center of the necklace. When she went to the pier, on the way there she met Nat and Ducky, she thanked Ducky for everything then she ran to the edge of the dock. She sighed, she controlled her thoughts to turn her into a mermaid and after that she did! She swam deeper and deeper until she reached the sea floor. She asked for sea creatured if they knew where Prince Lucky lived and all of the creatures told her to keep going forward. Cathy followed the sea creatures' directions then she reached the Kingdom of Goldtina, she was amazed on how the castle is made.
