Elmer and the Lost Treasure by David McKee

Elmer, Wilbur and a brave troop of elephants set out on a quest to find the famous Lost Treasure of the jungle. When they stumble across a beautiful forgotten temple, Elmer's friends rush inside, keen to find the Lost Treasure before him, but Elmer appears to have stopped searching...
A new tale from master-storyteller David McKee that delivers just as much pathos as the very first, this is the twenty-eighth Elmer storybook.
