Meet Nemeron and Pilon, two friends, an elephant and a tiger, who together learn, grow, sometimes get into trouble, and always have fun. In the Playground Builders, the friends are reminded about the spirit of sharing.Note to parents: The adventure picture books in rhymes integrate critical thinking, problem solving and pure reading enjoyment. The beloved series is the product of collaboration between acclaimed illustrator Dr. David Lobel and prolific writer Professor Orly Lobel.As all the Plion and Nemeron series, the books are harmonized with common threads, e.g., an excerpt from an eminent poem; rhythmic pattern openings. In the tradition of the beloved Dr. Seuss, Madeline, Bernstein Bears, and Curious George series, these fun threads give young readers consistency and familiarity.
