Glad to hear, you solved that problem....But now I'm curious...

.. Facing the coin slot and counting left to right, I've
always found the idol in the 5th room. You say you found it in the 2nd room...is that also counting left to right?
BTW...if you're a treasure hound..you might want to check out one of the games forgotten/secret areas, when you go back to the temple. (There are 4 chests hidden here)
In the room where you found one of the monkey idols, (the one that is accessed through the kitchen) if you stand next to the chest and face south, when you look up...you'll see a wide brown strip. That is actually a ledge and the entance to the '
Belfrey'. If you stack crates next to the chest and jump up...you can get on top of the ledge. If you can't jump that high...you can bring up some of the crates from the next level down. (easiest way is to carry them and walk backwards onto the elevator)
I think this is another one of the '
Left over' areas that was never finished, when they rushed the game for release.
