Based on Marc Brown's classic Arthur books and the PBS KIDS® hit show. Arthur, D.W. and their friends can race to the tree house on their bikes, climb high into the branches, hang out in the tree house, swing on the rope swing or climb the rope ladder. Read the included Arthur's Tree House storybook to get playtime started! All pieces are made from Storytime’s unique combination of premium yoga/baby mat material (EVA foam) and high quality card stock. The treehouse house and characters fit together like a 3-D puzzle and fold flat in a travel-ready carrying case, conveniently designed to fit on your bookshelf. Assembling is as easy as pressing tabs into place. No tools or screws required.
