Book 11 in the Grumpy Monkey series celebrates fathers and grandfathers in this seasonal companion book to the Mother’s Day title. Jim’s dad LOVES Father’s Day, but Grandpanzee thinks the holiday is “a bunch of malarkey!” While Chip likes to be the center of attention, Grandpanzee prefers a day of termite fishing alone with his son and grandson. An enjoyable read aloud for 4-7 year olds and begs to be followed by a conversation about different emotions and reactions. And we learn where Jim gets his grumpiness from!
