I am getting frustrated with my village due to not being able to find rare collectables. I am missing one butterfly, one seashell, and 4 pebbles, and they NEVER come out. Any suggestions on how I can maybe aquire these collectables? I noticed with the bugs, that my population was able to grow. I am anticipating the next level up on population growth.

Any suggestions can be emailed to me at william.p.jones@gmail.com

Try checking the VV2 Guides sction of the forums. If you are unable to find your answer there, then here's a hint:
If you have the third level of exploration, you can see collectables on the map view. Just be sure to refresh the map about every 30 seconds.
