Stan and Jan Berenstain launched the Berenstain Bears books in 1962 with The Big Honey Hunt. Since that time, more than 365 Berenstain Bears books have been published, making it one of the best-selling children's series ever. Today, Mike Berenstain continues his parents' tradition of creating warm and engaging stories featuring the lovable Bear family-now in a brand-new board book format. In The Berenstain Bears Clean Up, the cubs learn that cleaning up is easy to do when everyone works together. The short, simple story and well-loved characters provide toddlers with a perfect introduction to this valuable life lesson.
