is a long line of Smurfs at the tower's door. Each Smurf is guided by Dopey Smurf, one at a time, through a long stair, and Brainy Smurf awaits upstairs, in a new costume, where he allows the corresponding Smurf to ask the book a question. After some time, dependence on the book escalates to a point where nobody does anything without asking the book first, and Smurfs do anything the book says; Potter Smurf digs another Smurf's garden because the book told him there was the best clay, and Vanity Smurf cuts flowers from Smurfette's garden because they are needed for a formula told by the book, for an ointment that erases wrinkles around the eyes. Flighty Smurf doesn't know what to ask to the book, until he leaves the tower and remembers he wanted to ask for a method to improve his memory. Another Smurf asks for a way to have Smurfette love him, and the book tells him Smurfette will love him if he gathers the qualities of all the Smurfs, and this makes Brainy Smurf realise that he should ban certain questions (because Smurfette should love him). Dopey Smurf asks the book for a way to rest from his job guiding Smurfs through the stairs, and the book suggests he exchange places with Brainy Smurf from time to time, which Brainy Smurf dismisses as a joke, but at least offers to finish for that day after seeing one more Smurf. Then Jokey Smurf asks the book how could he ask it questions without Brainy Smurf being involved, so Brainy Smurf angrily closes the book and the tower is closed for the rest of the day. Chef Smurf makes lentil soup for all the Smurfs, while Brainy Smurf gets a pastry with morel mushrooms, and Dopey Smurf (who, as the assistant, also has privileges), asks a piece of melon for dessert, but the "melon" is actually a pumpkin. Papa Smurf returns to the Smurf Village and finds the Smurfs have been using the Book That Tells Everything, and explains to Smurfette and Vanity Smurf that the book answers every question, yet without warning about the consequences of the solutions used (for example, Vanity Smurf's ointment did what the book said, but also gave him horrible button-shaped marks, so he's wearing a bag on his head, and the one that made Hefty Smurf stronger, now causes him so
