Gerbils to me. I remember when the gold/silver/crystal boards first had it's dog/cat arguments.. It was a huge pain in the ass with topic after topic arguing about what the trio were. Some started calling them gerbils in an effort to stop the thick-head folks from fighting. And sure enough, it worked! Hell even I agree they look nothing like gerbils. But that wasn't the point. The point was that it stopped endless flame wars. Simple as that really. Call them what you will, just don't start arguing over something pointless and respect others opinions, especially since the trio have never been officially claimed to be anything but Pokemon.
What's this about the Mocking Bird being the State Bird of Texas? Everyone should know it is the Mosquito.
