1. Press Triangle/Y, Press X/A, and open the Krypt it lands on. Repeat until entire Krypt is unlocked.
It's sort of faster this way AND I didn't run in to any Goblins. I started using that method after about only 10% unlocked (I only went for the costumes to begin with).
man they should at least have a way to turn that off or at least give out a warning to people with heart conditions or something... i can't stand those things!
