Yup, it's live (and if like me you check the forum before entering the world) now is the time to collect :)
Go squeeze a chicken (but more likely many chickens, unless the first four you get are all different)
Yay chocolate bunny! I think one of each type of egg was consumed by the creation of my trophy. At least, I think I only eat surprisingly large amounts of chocolate in real life.
I'm finally in game! I collected 3 eggs, more 2 to go! I hate squeezing chickens! I'll make sure to try harvesting eggplants too though! I need that bunny!!!!!!!
There are 5 kinds, and when you get the trophy it EATS the 5 different eggs. Fortunately, this just gives you an excuse to start collecting another full set.
