The Underwater Mailbox

This audiobook is narrated by an AI Voice.
Deep at the bottom of Coral Canyon stands the world's wettest post office — a rusty old mailbox — and Marlin, the fastest (and most distracted) mailfish in the sea. Every Friday, lonely lighthouse Keeper Sol drops his letters into the ocean in sealed glass bottles. This Friday there's a special one: a hand-drawn birthday card for his granddaughter Isla, who turns seven tomorrow. Marlin tucks it safely into his satchel and promises — cross his fins — that it will arrive on time. Then the storm hits. Letters scatter across the canyon, and Marlin must rally the whole reef — Octavia the eight-armed octopus, the seahorse twins, grumpy Grumbles the crab, and Pippa the pelican — to deliver every last letter. A heartwarming ocean adventure about how it takes a whole reef to deliver one special letter. score tracker, a storm maze, 2 coloring pages, spot-the-difference, connect the dots, a match-the-letter game, ocean-mail jokes, a draw-your-own-letter page, and a full answer key!
