Narnia Spy Shad E. wrote, letting us know that his brother found a couple of Narnia games hidden on the official Narnia website:
My younger brother went to the Narnia site to play that “Enter Narnia” Game (the one were you search for the hidden Narnians). He found two other games hidden inside the first one. The first of the two can be found in the “Beruna Woods” and is called “Castle Escape.” (click on the horse or this link)
