After seeing the books, Think-Tank initially calls them sandwiches. He further tells his crew members that sandwiches are the staple diet of the Earthlings. He ordered Captain Omega to eat one of them and confirm his opinion. Captain Omega further orders Lieutenant Iota who orders Sergeant Oop. It is Sergeant Oop who finally bites the book. He tells them it is not delicious at all and that he is surprised how the earthlings eat it without water.

Noodle guesses that earthlings didn’t eat the books but used them as communication devices. The crew members put the books at their ears and try listening to them but couldn’t hear anything. Noodle further suggests that they were for visual communication.
