Toys don’t just free children's imaginations; they also impart valuable lessons, such as how to share and what to do when the family dog morphs into a sports car. Prepare little ones for shape-shifting eventualities with today's Groupon: for $15, you get $30 worth of toys and games from HasbroToyShop.com.

Generations of children have delighted in Hasbro's toys, which have included such iconic characters as MR. POTATO HEAD, G.I. JOE, and TRANSFORMERS. The PLAYSKOOL PLAY FAVORITES LULLABY GLOWORM toy ($11.99) has a huggable body and six different soothing songs, granting babies easy Z's and baby sitters an evening break from performing Madame Butterfly for colicky audiences. A NERF SUPER SOAKER THUNDERSTORM ($14.99) provides older children an invaluable tool for tree-house defense, and board games such as SCRABBLE ($14.99) engage youngsters’ competitive urges in a more healthy manner than moping contests and water-balloon arms races.

HasbroToyShop.com allows perusers to shop by age, toy category, or brand, making it easy to quickly track down a birthday gift for a favorite nephew or a 50th-anniversary present for a spouse aging in reverse. Shipping is not included, but this Groupon is valid toward shipping costs.
