The family enjoys sailing their boat "Vega Dos" in the Mediterranean Sea. They observe many animals including colorful fish, dolphins, seagulls, and pelicans. One day they saw sea turtles swimming between the waves. While sailing, they decided to go fishing and unexpectedly caught an old boot, a beer can, and lots of plastic trash someone had dumped in the sea. Tired of removing rubbish, they put on goggles and snorkels to swim and see tomatoes, sea urchins, stars, and crabs. They also observed two angry octopuses squirting ink. Later on the beach, they built a sandcastle and looked at the sky, imagining what the clouds formed.
