I recently discovered a great easter egg in VF!
How to access it:
Open VF. Click "Menu." You will go to the screen that says "Virtual Families." Mouse over the butterflies in the bottom right hand corner. Voila! They will start to follow your cursor!
Awesome huh?
PS. They are the also the butterflies that you try to catch in Plant Tycoon

I knew about the butterflies in Vf but not in plant tycoon !!!!

Cool
If you knew about this please comment, I'm anxious to see who already figured this out :P

I've known about the butterflies in VF for quite some time now and I just figured that everyone else did too!

I always noticed the following butterflies, but I don't think I ever clicked anywhere.

I think this is like some websites where stuff follows the cursor. I think it's really great!

I've known about the butterflies from the beginning. They're just an animated image that follows the cursor as Moonlyght stated above.

I have known about it from vv vv2 and vv3!
plus vf TOO!!!

Aww darn, it's not so secret after all

Kind of cool though.

i've known about the butterflies , i like to spend few seconds playing with them before i move from a family to another

In,all the VV games and in VF has the butterflies,always when I first get the game,I just like checking them...
