DUPLO My First Shape Sorter: Puppy House 10441 Building Kit (17 Pieces)Lift the lid on a whole heap of puppy play with this colorful shape sorting toy. Preschoolers build a place to play under the trees, then throw the pups a ball to chase or feed them a bone. Toddlers can have fun and learn skills as they drop the shapes into the holes in the lid, which attaches firmly to the bowl so they can tidy away their bricks when playtimes over.
