Poodoku

Described by the author as “packed full of Sudoku puzzles [and] poo facts,” Poodoku is, at the time I’m writing this, the #63-best-selling Sudoku book on Amazon. I mostly posted it here for the cover, which, as you can see above, includes a Sudoku puzzle that’s entirely pixellated, and a pre-shitted roll of toilet paper seemingly drawn with Paint.
