How do you get the warrior mask on time tangled island?

You actually need to get the Warrior mask to recover the goggles for 1953 AD. In the Aztec time, 1519 AD (5 o'clock on the time device), go to the top of the 3rd temple and talk to the old warrior there. He will give you his warrior mask. (Now you can get the goggles from the hostile guard.)
