Looking for a children's picture book written in the 1980s, possibly late 70s or early 90s. The book we had was hard-backed, medium sized average children's book. NOT a toddler or baby book. Illustrations were colorful, and detailed. Almost resembled Where's Waldo but not quite as intense. Images included illustrations of beach animals, shells and sand. and I remember beach trash was involved as well. The main character was a bald or short haired white boy. He might of had a dog. I am almost positive that the boy's name was Sam, Sammy or Samuel. I also remember that he doesn't like the beach at first, and at some point in the plot, he has a problem with an octopus. That's all I can remember. Both my sisters and I vividly remember this book, but cannot find it anywhere. We thought it was called something to the effect of "Sam and the Seashore" but a google search yields absolutely no results. It's been driving us nuts! Please help!
