Thanks to the Collections section I have developed OCD. I am down to needing 1 in all but one of the collections where I need 2. They keep repeating and repeating and repeating...ARGH!!!!! Will I ever get all of them or should I just let it go?

go for it !!!! it took me 2 days to find the last pebble!!!

I'm getting really discouraged: for the past 3 days, I've been waiting and waiting for the last shell and the last two beetles, but they just won't show up.

Right there with you guys... I have been waiting for a rare shell for about 4 days now.... and nada!

I think the problem is, you guys are going to sleep. That's when they show up. You need more caffeine.
