Flat Stanley and the Lost Treasure (I Can Read Level 2)

Sometimes being flat comes in handy for Flat Stanley—like when he is surfing or rescuing a trapped dolphin from a net. In this exciting adventure, Flat Stanley and his brother, Arthur, find sunken treasure in an old shipwreck. But Stanley has to get rid of his gold bar in order to squeeze through the net and rescue the dolphin. Will they ever find the treasure again?

This is a Level Two I Can Read book, geared for kids who read on their own but still need a little help.
