Jade and the Tide-Pool Riddle

Can you spot the pearl? Jade could see shells everywhere—but not the one she was looking for.

She peered into the shallow tide pool beside the mermaid village. Smooth rocks made a little bowl around it, and tiny waves slipped in and out through a narrow gap. The pool was full of pale shells: striped ones, spotted ones, and shells so round they looked like little moons.

“I set my pearl right here,” Jade said. “Beside the flat rock with the green seaweed.”

Her cousin Zeke swam up, holding a small basket. “I’ve looked under the rock and around the seaweed. No pearl.”

Jade patted the pouch at her waist. It was empty. She had meant to put the pearl away before they left the pool, but then a tiny crab had marched past wearing a leaf like a hat. Jade had laughed, and when she turned back, the pearl was gone.

“Maybe the crab borrowed it for a button,” Zeke said.

They both peeked beneath the flat rock. The crab was there, but its shell had no button. It lifted one claw as if to say, “Not me,” then scuttled into a crack.

Jade studied the pool. “Let’s make a riddle. What are we looking for?”

“A pearl,” said Zeke. “Small, pale, and smooth.”

“And what makes it different from these shells?” Jade asked.

Zeke picked up a curved shell. “This has a point.”

Jade held up another. “This one has stripes.”

They set each shell down gently. The pool’s water wobbled around them, making every shape look a little different. Jade squinted. “Our pearl is round all the way around. No point, no stripes.”

“Then we’ll find the one round thing that doesn’t belong,” Zeke said.

They searched between the rocks and beside the seaweed. A round shell rolled in a slow circle. Another hid beneath a curled ribbon of kelp. Jade checked them both. Shell, shell, shell.

She glanced toward the village path, where their family was waiting to head home soon. “I want to find it before we leave,” she said.

Zeke nodded. “Then we’ll keep looking. Riddle eyes on!”

Jade leaned close to the water. The tide slid into the pool, swirled around the shells, and slipped back out. For a moment, something beneath a wide, scalloped shell seemed to move.

“Did you see that?” she whispered.

The shell settled still. Jade and Zeke bent nearer. What could be hiding underneath?

Jade and Zeke searched the pool again, carefully this time. They checked each round shell against the riddle: no point, no stripes, smooth all the way around. But every shell had a little ridge or a tiny mark, and the pearl stayed out of sight.

“Maybe it rolled into that crack,” Zeke said, pointing between two rocks.

Jade looked into the narrow space. It was too dark to see much, and the opening was too small for her hand. “It might have,” she said. “But I don’t want to poke and bump anything. Let’s watch the water.”

They waited beside the pool. A small wave slipped through the gap between the rocks. The water curled around the scalloped shell, lifted one edge, then flowed back out. The shell rocked once and settled again.

Jade’s eyes widened. “The water is showing us what’s behind it!”

Zeke leaned closer. “I saw a little white bit.”

“Was it round?” Jade asked.

“I couldn’t tell. The shell covered it again.”

Jade considered the shell. It was wide and heavy, but the moving water could lift its edge just a little. “When the next wave comes, we can help it turn. You hold that side, and I’ll hold this one. Slowly.”

They placed their hands on the scalloped shell, ready to guide it without scraping the rocks. The next wave slipped in. Water gathered under the shell and raised it a finger’s width.

“Now,” Jade said.

Together they tipped the shell onto its side. It rolled gently over, making a soft plop in the pool. Behind it lay a small, smooth shape, nestled in a dip between two stones.

Jade didn’t grab it right away. She looked closely. “No stripes. No point. Round all the way around.”

Zeke grinned. “That sounds like our answer.”

Jade reached down and lifted the pearl. It was cool and slick from the water. She rubbed it with her thumb, then turned it in her palm. “My pearl!”

Zeke gave a quiet cheer. “The tide gave us a clue.”

“And we remembered the riddle,” Jade said.

She opened the pouch at her waist and slipped the pearl inside. Then she tugged the tie snug and checked it with a gentle pat. The pearl was safe. The scalloped shell rested on its side, and the little wave slipped through the rocks once more.

“Ready to go?” Zeke asked.

“Ready,” Jade said. This time, she kept one hand over her pouch as they swam away from the tide pool.

Jade and Zeke followed the smooth-rock path back toward the mermaid village. The water was calm around them, and a few strands of sea grass brushed their shoulders as they passed.

“Do you think the pearl remembers being under the shell?” Zeke asked.

“Maybe it remembers the waves tickling it,” Jade said. She touched her pouch to be sure it was closed. “And maybe it remembers us solving the riddle.”

At the edge of the village, they passed the crab with the leaf hat. It was sitting on a stone, polishing one claw. Jade gave it a little wave.

“Still no pearl button?” Zeke asked.

The crab tapped its claw on its shell. Tap, tap. It looked rather pleased with its hat.

Jade and Zeke giggled, then swam on. Their homes rested among curved stones and waving sea plants. A few family members were waiting nearby, and Jade showed them the tied pouch.

“I found it behind a scalloped shell,” she said. “The water lifted the shell just enough for us to see.”

“Good looking, and good thinking,” said her aunt.

Zeke added, “And excellent riddle eyes.”

Jade opened the pouch just a crack so everyone could see the pearl. It sat safely inside, round and smooth. Then she closed the pouch again and tucked it close.

The village grew quiet as the mermaids settled in for the night. Jade rested on a cushion of soft sea moss, while Zeke curled up nearby. They talked in low voices about the tide pool: the striped shells, the crab’s leaf hat, and the wave that had lifted the hiding shell.

“Tomorrow,” Zeke murmured, “we can look at your pearl again.”

“Tomorrow,” Jade agreed.

She rested her hand over the pouch. There was no need to search now. The pearl was right where it belonged, safe beside her. Outside, the tide moved gently past the village rocks, in and out, in and out. Jade listened to its quiet water-song, while the smooth stones held the little homes close and the sea carried the night along.
