McDonald's is encouraging children to read about healthy eating habits.
The fast food chain announced plans to replace Happy Meal toys with four original children's books that carry a positive nutritional message for the first two weeks of November.
The paperbacks, which can be found inside the little cardboard boxes from Nov. 1 to 14, will be published by McDonald's and will feature new characters to help kids learn about healthy eating.
Some of the stories include: a goat who overeats but learns the value of a smart eating habits, and the world's smallest dinosaur who grew tall by eating well.
McDonald's expects to deliver 20 million books in the two-week span.
"We think that this is a fun and engaging way to give a nutritional message to kids," Ubong Ituen, vice president of marketing for McDonald's USA, told Ad Week. "This is really the first step in a larger book strategy, and our intent is to continue over several years."
