No, this is NOT clickbait. So I had just bought a cracked egg, and two people tried to trade for it, but I declined because I don't like to trade pets. And boy, that was a great decision. When the egg hatched, it turned out to be a legendary Alicorn, which had just been released into the game. Only half a second passed, and suddenly, pretty much everyone on the server was making offers for my Alicorn, which I still refused. I went to my house, which was being used as a pet sitting site, and named the Alicorn Drake, and then, just for fun, logged on to another server to see how many people would attempt a trade. So yeah. I got extremely lucky, and now I can't age up Drake without getting 100+ trade offers.
Update: I traded Drake for a pair of mummy cats. It was a good offer.
