You should think of advertising your link online as I said. I'm already at 400 refs, got 300 from adds that I bought for like 50$
I got one for myself also and bough my gf one :) Let's hope they hatch something cool, btw they can be boosted to get a rarer pet. But that will be avilable only when the game starts in a couple of days. We will get notified by email I think.
