At Vermifuge the Red's Egg Agency, you can adopt eggs. Sometimes you know what's going to hatch, sometimes you don't!
I adopted two eggs from Vermi, a Dragon egg, and an unknown egg. They hatched on December 24th, 1999!!

My Christmas Dragon! (Hatched Dec. 24th '99)

I'm so lucky! I got a Hippogriff! (Hatched Dec. 24th '99)
