Dear Tuna Puzzler - you made the following statement above and I am amazed!

"Anyway, after you get your last power you'll find all those uncommon and rare collectibles, so don't worry too much about the ones that get lost."

Are you saying that what powers you have relate to what collectibles show up? I've had earthquake power forever and am still not finding all the collectibles. Am I supposed to do something with it besides impress and convert heathens?
