Filled with humor, energy, and warmth, this is a story about a child spending time with his grandpa. Written in a how-to style, the narrator gives important tips for "babysitting" a grandpa, including what to eat for snack (anything dipped in ketchup, ice cream topped with cookies, cookies topped with ice cream) what to do on a walk (find lizards and dandelion puffs, be on the lookout for puddles and sprinklers), and how to play with a grandpa (build a pirate cave, put on a scary play).

From the author-illustrator team behind the New York Times bestselling HOW TO... series comes a funny and heartwarming celebration of grandpas and grandchildren.
