Escape Quest Level 7 Walkthrough:
Put the calendars onto the whiteboard, then repeatedly tap each calendar until the numbers stop changing.
The code is 683 cat, where cat = 38 (shown by picture on wall).
Put the last item you have onto the window and it'll show you how to position the books on the bookshelf.
Once the drawer opens below, enter 68338 into the white box.
Proceed to the next Escape Quest level!
