Is is easier to find them BEFORE you clear the mosaic? I saw something in a post about finding them before they cleared that up, and I am sure having a hard time finding the last 3. I got it down to 3 TODAY after not finding a new one for at least 8 days.

It is basicly just luck. I started apost about my last pebble and beetle collection. It took me over a month to find both these collectables but it was worth it!!! I also had my mosaic uncovered when i found the pebble. Just keep checking for the missing collectables and you will eventually find them.

GOOD LUCK!!!!
