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

Second, u 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, u need to complete it witout losing a sub. u can do this in step one of two, of if u didn't get it then do it now. if u don't do it, u can't verplaats on to step four.

Fourth, u have to do it timed. During that time, u may see the giant squid. (Check foto's to see what it looks like!!)

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