Sammy the Seahorse Solves the Sandcastle Secret

Sammy the Seahorse loves the peaceful mornings of Coral Cove, but his calm routine changes when he notices strange, darting shadows moving unnaturally across the sandy seafloor near an old sandcastle ruin—shadows that behave as if they have purpose but no visible source. Curious rather than afraid, Sammy investigates and discovers something even more unusual: a hidden, glowing object buried in the sand that seems to respond to him with a soft chime and pulsing light. As he carefully digs it out, he realizes the mystery is far bigger than it first appeared, pulling him into an unfolding underwater adventure filled with secrets, strange phenomena, and the sense that Coral Cove itself is hiding something important waiting to be uncovered.
