You can navigate that but can't walk??

I pushed all of carson's toys into the corner so I could evaluate what would be put up and opened so we can rotate toys... After the birthday we are at that point! Carson maneuvered all of these toys and chase said, "you can navigate that but can't walk yet?!" I laughed as we watched him climbing toys like stairs to reach other objects! Then I realized he could get lost in the toys... Where's Carson? It's like a real life version of where's Waldo!
