Introduced by Hasbro in 1991 and reintroduced in 2013 by Just Play, Puppy Surprise™ went on to become one of the best selling plush toys in history. 'Surprise, surprise it's Puppy Surprise, how many puppies are there inside. Will there be 3 or 4 or 5?' A pregnant Mommy dog with surprise puppies inside a velcro-enclosed pouch became a toy craze that is still an evergreen product today. Puppy Surprise and the family of Surprise brands (Kitty, Bunny, Unicorn, Pony etc.) has sold over $500,000,000 at retail.
