One sunny morning, Nadine put on her blue starry dress. She went to play by the sea. The waves went splash! A magic shell sat in the sand. It was pink and shiny. Nadine picked up the shell. It began to glow! A soft voice came from it. "Dear Nadine, the sea needs your help! Would you like to go on an adventure under the waves?" Nadine's eyes got big with wonder. She loved adventures!

"Yes!" said Nadine with a big smile. She held the shell close. The shell glowed brighter and brighter! Sparkles flew all around her. Like magic, Nadine could now breathe under water! She stepped into the waves. The water felt warm and nice. Down, down she went into the blue sea. Fish of all colors swam by. They waved their fins at her. A small blue fish stopped near Nadine. "Hi! I'm Finn," said the fish. "We need help! The baby sea turtle can't find his way home. He's lost in the dark cave or the kelp forest."

Nadine and Finn swam to the dark cave. The opening was big and round. It looked a bit scary, but Nadine was brave. "Don't worry," said Finn. "I can glow in the dark!" His scales lit up like tiny stars, just like the ones on Nadine's dress. They went into the cave. Drip, drop went the water. Their eyes got big as they saw pretty crystals on the walls. "Hello?" called Nadine. "Little turtle, are you here?" They heard a small sound. Behind a rock, they found the baby turtle! But oh no - his flipper was stuck under some stones! "I tried to swim through," said the baby turtle with tears in his eyes. "But the rocks fell down!" Nadine looked at the rocks. She could try to pull them off by herself, or she could look for help from other sea creatures nearby.
