I am still amazed at how cute the brown plaid bunnies are. Of course, it's always a problem when you know they are cute, they know they're cute, and they know that you think they're cute. Let's call it the Roy effect.
And since bunnies are "friendly," they want a larger and larger party. Also, the original brown plaid bunny (top right) objected to having a polka dot background, so he was transplanted to a plaid background. Now each bunny gets to pick his own plaid background before he moves in.
