What are Janis Elspas's most significant collaborations with National Geographic Kids?

Based on the available content, Janis Elspas has collaborated with National Geographic Kids on a giveaway. She hosted a giveaway for MBE's animal lovers, where participants had a chance to win a children's hardcover book prize package from National Geographic Kids. The package included three hardcover books: "We Love Babies," "1000 Facts About Dinosaurs," and "Turn it Up History of Music."

However, I don't have detailed information on other collaborations between Janis Elspas and National Geographic Kids. Would you like to know more about the giveaway or other activities Janis Elspas is involved in?
