The 30th Elmer storybook, written by renowned picture book author and recipient of the BookTrust Liftetime Achievement Award David McKee, is about taking care of elderly relatives. Elmer's Grandpa Eldo sent Aunt Zelda a present, but she can't recall what it is or where it is. Together, they set out to find Grandpa Eldo and unravel the riddle of the misplaced gift because Zelda often has trouble remembering things and her hearing isn't as good as it used to be. In his 30th book, Elmer paints a heartwarming picture of family life with ageing relatives via his love, tolerance, and respect for his Aunt Zelda and Grandpa Eldo.
