Finny the rainbow fish shimmered with every color you could imagine. He loved swimming around the coral reef, greeting all the other fish. But one day, he saw a shy little crab hiding behind a rock.

"Hello there!" Finny said cheerfully.

The crab peeked out with one claw. "Hi," he mumbled quietly. "I'm Shelly."

"I'm Finny," the rainbow fish replied. "Why are you hiding?"
Shelly blushed red. "I'm scared of the bigger fish."

Finny smiled. "Don't worry, Shelly. I'll be your friend! We can explore the reef together."

Shelly hesitated, then peeked out again. "Really?"

Finny nodded. "Come on, let's go!"

Shelly slowly followed Finny, feeling a little less scared. They had a wonderful time exploring the reef together, and Shelly learned that not all fish were scary.
