The answer is THRONE
The corresponding square is house puzzle
   by Brian Tivol

The paint-by-numbers, snakes, and train puzzle can be solved as
written.  For the word search, use the words "ONE" through "NINE", as
used in the train puzzle.  The word search suggests that you use the
PBN as a criss-cross puzzle (again using the same nine words), and
then overlap all of the grids.  The criss-cross letters that line up
with the snakes' heads, taken in the order of the train tracks, spell
the answer.

PBN (with filled-in numbers):
