Rain streaked the window. Tilly thought of Grandma’s bedtime stories about faraway places. “Could they be real?” she asked. Grandma smiled from her chair. “Why not explore the attic?”

Up in the attic, Tilly opened an old trunk. Inside lay a folded map. She spread it open. Eight little doors circled the oak. Then the blue door began to glow.

Tilly followed the map down to the oak’s roots. There, tucked between them, was a real blue door. She had never seen it before. Holding the map close, she opened the door and peered in.

A shimmering bubble wrapped gently around Tilly. It carried her down through the blue door and into a sunny sea. Tilly smiled at the little fish swimming below.

Near the kelp, Tilly spotted a little turtle hiding behind a rock. “I’m Nami,” she said. “My family is waiting beyond the kelp, but it swishes and shadows me. I’m too scared to swim through.” Tilly smiled kindly at her.

Tilly felt scared too. She reached one paw out through the bubble. It stretched softly around her wrist. “Let’s be brave together,” she said. Nami reached for Tilly’s paw.

Nami held Tilly’s paw, and they swam into the kelp. “Together, together,” they sang. The swaying ribbons brushed past. Tilly giggled. They were tickly, not scary! Their song carried them through.

At the far side, the reef opened in bright colors. Nami spotted her family and swam joyfully toward them. Her mama and papa hurried to meet her. Tilly floated nearby in her bubble, glad they had made it through together.

Nami gave Tilly a tiny spiral shell. Tilly held it to her ear, and it hummed softly. “I’ll remember our song,” Tilly said. Nami smiled beside her.

Tilly said goodbye to Nami and floated back through the kelp. She held the shell close in one paw and waved with the other. Soon, the blue door was waiting ahead.

The bubble carried Tilly up through the blue door. Grandma waited beside the roots with a smile. Tilly stepped out, still holding the map and shell. “Just in time for supper,” said Grandma.

That night, Tilly set the shell on the map. The white door began to glow. She looked at the little acorn in the corner. “Who drew you?” she wondered. Then Tilly fell asleep, ready for the next door.
