Deep in the blue ocean, a tiny shell blinked with soft light. Fofo saw it and swam closer.
The shell's glow danced past swaying seaweed and a crab with a cross claw. Fofo followed.
A current pushed Fofo sideways. But the shell came back, humming a bubbly tune.
Fofo giggled and swam after the sound. The shell glided lower, lower...
The shell settled onto the sand. A circle of light appeared. Something peeked out.
'Hello?' whispered the seahorse, in a voice like wind chimes.
Fofo nudged the sand softly. The seahorse uncurled its tail and smiled.
They swam a slow circle together. The shell glowed brighter, and brighter.
