Role in the episode
When SpongeBob is supposed to Moonwalk on Squidward's treadmill, Squidward goes away to read this book. It is unknown what it is about, but it can be assumed that there might be snail shells in it. It may also be a guide book full of seashells. He might have been reading because he wanted a shell for Snellie. Squidward obviously had this in his book room.
