Mirika is on her field trip to Rabbit Museum. There, they have a tons of rabbits and some might be poisonous! Mirika thinks that it will be a great trip but will you wonder about her fate? She is partnering with her big sister, Miwi and she has nothing to worry about but she has not realized that somebody out of nowhere was looking on her. Miwi is a fashionable idol and the guards let them in. Mirika looks at a rabbit in a cage. The rabbit was sleeping. Mirika in a loud voice says, ''A very very cute rabbit! Can we keep it?'' The rabbit woke. ''Y E S'' says the guards. ''Thank you. My little sister will be happy after all, she likes rabbits the most!'' Miwi said. ''Thank you very much!'' Mirika said. The guards were surprised by her marvelous cute looks but it was of course, the face. Mirika kept the rabbit in her two arms. Labumi who was the rabbit kept a eye on her because she was so interesting. Mirika said, ''I'll be looking for more rabbits on the field trip. I'll let you know when I see another cute looking one!'' ''Of course, don't get lost!'' Miwi said back to her. So Mirika and Miwi walked in different directions. Labumi started talking and he flied. ''Actually, my true identity is that I'm a fairy!'' Mirika was shocked. ''Ah-a talking rabbit!'' she shouted. ''I'm no rabbit!'' Labumi shouted. ''Of course you're not. Unbelievable creature!'' Mirika argued. ''What did you say!? When you called me very cute!'' Labumi argued back. Mirka frowned. Labumi felt a bad feeling and thought that there was a Yabaina. She said, ''There's a Yabaina!'' and gave Mirika a locket. ''Yell out, Petin Petin Unique!'' ''I don't know what's going on but I'll try!'' Mirika held up her locket and shouted, '' Petin Petin Unique!'' She was transformed. She raised her arms and moved her left arm to her hips- her right arm making a peace sign saying, ''Swamp cherry blossoms, Cure Petal!'' Cure Petal moved forwardly and punched the Yabaina in it's eye. The Yabaina got pretty much of a damage. ''Cure Petal! Use that locket and pray- then say, Petal Clone!'' Labumi said to her. Cure Petal followed Labumi's directions and it directly harmed the Yabaina. ''One day, I'll beat you! Pretty Cure!'' said Kaisen, an averaged servant to his lord. Cure Petal transformed back to Mirika. Mirika was really exhausted and Labumi returned into the locket. Right there, Miwi found Mirika laying on the ground and she took her to the nurse and they said that she was okay. It was going to be a day-for like someone who turned into pretty cure.
