Where is the dollhouse door in I Spy Year Round Challenger pg 26 and 27?

"on the left hand side of the page in the top left window, i think there is a dollhouse with a door" - other user's answer

I could be wrong, but I believe that the item in the upper-left window is actually a bird cage, and is the answer to "cage". I, myself, am having difficulty locating the dollhouse door - unless the author is referring to the very obvious door located on the large haunted-looking dollhouse he has constructed.
