still stuck on shark island

[beth]

I found 2 valves, alot of shells and 3 crystles pink, blue & yellow. Stuck after putting in the 2 valves, what do I do next. I think froglady said something about a engry crystle, but can't find it ,so can' t get anywhere else. And also love this game, but very frustrated. Really would like more help please. Love the spoilers.
