To use this zoo block set, simply take the blocks out of the colorful printed box and start building your own zoo. Let your creativity flow and create different animal habitats. As you play, you'll discover new ways to arrange the blocks. For kids aged 3 and above, adult supervision is recommended during play. When you're done playing, put the blocks back in the box to keep them organized. To keep the blocks clean, you can wipe them with a damp cloth. Avoid using harsh chemicals as they may damage the blocks.
