Where does this mythical exchange rate of 1 stripy egg to 1 coin come from ?
When it comes to Gene pools and shallow ends they can be found at the bar drinking pina colada's
UPDATE:
An update regarding the free building spots needed by the Achievement building has peen posted here.
Acquiring the building
The building will be available as a quest reward from the quest chain "For my most loyal egg hiders". The building will be an item in the Star Menu and can be placed on a free 3x3 spot. The building will be available after the Easter event 2015, independent of any achievements completed.
What does the above mean though in relation to being available after the event - a gem shop item?
I think option c is correct tbh
I reckon Option A as it will feed the gem sales. God forbid I am not exchanging my island of Frozen Manors for an Island of Egg Houses lol
