Meet the Characters
Coco the Crab
Coco can only ever walk sideways, and he often wishes he could swim straight ahead like his friends in the reef.
Sandy the Starfish
Sandy got herself stuck in a tight, narrow gap between two coral rocks, and she cannot wiggle free on her own.
The Story
Coco watched the fish zoom straight past him, gliding smoothly through the reef without a single sideways step.
“I wish I could swim straight like that,” Coco sighed, scuttling sideways across the sand, just like always.
No matter how hard he tried, Coco’s legs only ever moved one way, click, click, click, sideways across the ocean floor.
That afternoon, a worried cry echoed from a narrow gap between two coral rocks.
“Help! I’m stuck!” called Sandy the starfish, wedged tightly between the rocks.
A fish swam over first, but his wide body couldn’t fit through the narrow space at all.
An eel tried next, sliding in headfirst, but the gap was too tight even for him.
Coco watched them both try and fail, feeling a little useless drifting nearby.
Then he noticed something. The gap wasn’t too narrow, it was too narrow for swimming straight through.
“I might be able to fit,” Coco said, scuttling closer. “I only move sideways, after all.”
He turned his flat little body and slid sideways into the narrow gap, slipping through easily where the others couldn’t.
“You’re almost there!” the fish cheered from outside.
Coco reached Sandy and gently nudged her loose, sliding her sideways out through the same narrow gap.
Sandy popped free, tumbling gratefully into the open water.
“You saved me!” Sandy said. “Nobody else could have squeezed in there.”
Coco looked down at his own sideways legs, seeing them differently for the very first time.
“I guess sideways isn’t so bad,” he said, a little proud.
“Sideways is exactly what saved me,” Sandy grinned, and the whole reef agreed.

Moral of the Story
This crab bedtime story is not about wishing to swim straight. It is about what Coco discovered the moment his sideways walk was exactly what was needed. For little ones who wish they could be like everyone else, Coco’s rescue shows that being different is sometimes the whole point.
Reading Tips for Parents
