Familiars. As apparel often wasn't to my tastes, and I had so few dragons that gathering food wasn't an issue. But I remember being so excited to get a free podid, even though the person handing them out warned me I would be swimming in them soon enough. (And I was just a handful of months later.) I also still remember the first familiar I got. I was so proud of it. And so proud when I finally had enough familiars to give one to each dragon. Plus they gave treasure and chests which was super exciting to newbie me.

Granted, I was a newbie two years ago, so this has likely changed. But I thought I would throw my $.02 in. I'm interested to see what responses you get!
