This limited edition update was a small little update from May 9th, to May 11th. This update involved the Mexican worker guy, as he could build stuff faster, and you can buy another worker for only 25 clams!! Holy crap!
For example, if you wanted to build something, let's say that you want to build a furniture store, it is only 8:00:00 to build. But, with this update, you will only have to wait 4:00:00 for it to finish! Half of the time is gone!
If you want to build 2 things at once, you will need another worker. But the workers cost a lot of clams! That's a lot! But, in this update, you can buy your first worker for only 25 clams! Awesome!
