First, آپ have to get the main treasure that's in the big clam's mouth.

Second, آپ have to get the rare treasure. There are five tiny clams with tiny, white pearls. One has a black pearl, that is the main treasure.

Third, آپ need to complete it witout losing a sub. آپ can do this in step one یا two, یا if آپ didn't get it then do it now. if آپ don't do it, آپ can't اقدام on to step four.

Fourth, آپ have to do it timed. During that time, آپ may see the giant squid. (Check تصاویر to see what it looks like!!)

Fith, آپ have to do it in compressed air mode, meaning that آپ can't touch anything, otherwise آپ lose your sub. Plus, آپ -will- go very fast.
