That's cool, Mia, what a nice thing to do. I don't think I'll ever get an egg with my name in the code, lol!
Tru, Tawanda is a DC player, and I think she also plays Flowergame/posts in this forum. Dragon eggs don't have numbers like our flowers here, but a random series of 5 letters and numbers a.k.a. code. If you're lucky, the code of an egg spells a word or a name (e.g. I just got one with "sand" as part of the code). Some people even collect special kinds of codes, like all-number codes or codes starting with a z.
