By me and friends turning in eggs. And by Campitor saying so a few posts ago...
option 1 pet eggs seem to give like piece of cake, well baked cookie, candy, and rarely guarana candy
option 2 seems to be, guarana candy, buche de noel, candy, well baked cookie
option 3 can give trans candy (3)
that's what we've seen so far, which is pretty terri-bad
