“The Greatest in the World!” is the first book in the Tater Tales by Ben Clanton. Rot is a mutant potato students may recognize from the picture book, “Rot the Cutest in the World!” Rot is a cheerful, medium-sized and brownish potato, his brother Snot is larger, grumpy and greener. Tot is the smallest, with yellowish skin and a blue and white polka-dotted bow which matches the endpapers. 

In this beginning chapter book series, brothers Rot and Snot have a competition to decide who is the greatest in the world, to be judged by their little sister, Tot. When neither a potato sack race nor a game of hot potato produces a winner, they have a laugh-off, with an unexpected result. 

This book has five short chapters, ­and has some early graphic novel features with speech bubbles and vibrant illustrations. The end of the book includes “Spudtacular Facts”  as well as step-by-step instructions for how to draw Rot. This book introduces readers to Clanton’s new characters, who are just as silly and ­appealing as Narwhal and Jelly.
