How do they do that?? Hide things that are impossible to find??

Toto does it with anything paper that she finds ... she seems obsessed with paper! She had rather have a business card than a treat!

We will find a little piece of it ... just a word or two to identify what it "was". We will search and search for the rest of it ... days or weeks later we will be "rewarded" with another little piece ... if we saved them all it would be like a puzzle!!
