I've been curious about this since I set up my goals!
I think my silliest (and also top) goal is to have a G1 Bracchus named 'Bracula'. I thought of it at something like 3 am and couldn't stop laughing, and decided to make it one of my main goals here. It'll be a loooong time before I get one since I have pretty much nothing in the way of ms or pebbles but it's fun to think about.
What are everyone else's silly goals?
