I have just hatched with my fierce hound and my friends pet egg! And i ended up getting a pet egg ( yay! )! There is only a 2% chance that the other player will get the other persons pet. So i named my new pet egg Chance :). Goes great with him doesn't it? And my friend ended up get the same pet also his name is Oliver ( jr. ) but mine is the one with mixed talents. Because i leveled him up and got death shot. Which is the talent my Adult Fierce hound give me. Here is a screen shot of the newborn pet eggs!
And here are the 2 pets that made this possible!
Lol and we leveled them to teen in only 15 min!
This is Chance training. :)
Good luck all!
