Molly's mother takes Molly, Tooey, and Grandpa Nat to Sitka for the three of them to spend the weekend with Randal while Molly's mother and Randal's mother go away for the weekend. The trip to Sitka ends up being a twofer when Grandpa Nat looks forward to the harvesting of sea cucumbers (for a dish that involves sea cucumber as the main ingredient) at Crescent Moon Cove and Molly and Tooey hope to find petroglyphs (which they've been recently learning about in school) in the same spot. After getting an early start the following morning, which ends up with soggy sneakers, Molly and Tooey join Grandpa Nat and Randal in harvesting the sea cucumbers that wash up on the beach and learn about the sea cucumber's defenses as they go. Although they harvest enough sea cucumbers for Grandpa Nat's recipe, Molly and Tooey still want to find the petroglyphs, until they find something in Grandpa Nat's tide book that just might help them plan an earlier head start in the morning.
Molly and Tooey have been learning about petroglyphs, ancient stone-carvings, and can't wait to see them in real life on their trip to Sitka. But when they arrive at the beach supposedly covered in petroglyphs, all they see is water. Will they solve the mystery in time to see the petroglyphs?
