I definitely like Bob and Dale's more noticeable dancing avatars (above) as well. I used to find the pink elephant to be a little obnoxious and... well... pink
. But I've grown to love the little guy, just like it's owner - Bob!
Now I always know when Bob's around just by seeing the flashing pink anywhere on my screen.
But my favorite avatar, and the most scary, would have to be Mike's (Cyberscout):
Makes me want to go crawl into a corner and hide... Where's Mike been lately anyway? Haven't seen him around anywhere for quite a while. Mike, come back! We miss you buddy!
