It’s vacation time for Mili, Quesito, and their family! After traveling by plane, bus and boat, they arrive at a city by the sea where they meet a magical snail that takes them on an undersea adventure. They meet colorful fish, anemones with amusing hairstyles, a dolphin in trouble, a radioactive octopus, and a dirty raccoon who is in urgent need of a lesson.

A simple text with detailed illustrations keeps the book fresh after multiple readings.
