Experiencing occasional visions of the future, mermaid Kiki Coral receives a psychic warning that her classmate, Rocky Ridge, will have a dangerous encounter with a giant leatherback turtle, a premonition she fears nobody will believe.

Of all the creatures in the ocean, sea horses are Echo Reef's favorite. They're sweet and gentle and they glide through the water so gracefully. When Echo discovers that Rocky Ridge, one of her Trident Academy classmates, has his own pet sea horse, she wants one right away. Not everyone agrees sea horses should be pets, however. Perhaps they are happiest when swimming freely. But Echo thinks that if Rocky can make a sea horse happy, she can too!...

A sea horse leads the reader past coral reefs and underwater creatures to a sea horse family hidden in a cave. Includes notes on coral reefs and various marine animals.

Little Simon Seahorse likes to tell stories, and if some of them are embellished, it just makes for a better story; but when his lucky pearl disappears after Sea and Tell at Coral Grove Elementary he and his friends have a real-life treasure to find--and of course it will become a super story to tell, one that hardly needs embellishment.
