It's easy to create customizable habitats that pop! Use the included 3-D glasses to transform the three full-coluor pages (savannah, jungle, and ocean) into multi-dimensional scenes. The reusable stickers in this extra-large activity pad cling securely to the sturdy pages, and then peel off easily whenever kids are ready to make a change. Add details and animals on each page using the more than 100 coordinated stickers! 3+ years.
