Okay, so theres a Carpo, the kami of autumn and I don't know if I half to do all 3 of them or just 1 or 2 to get carpo to stay. Also I was wondering how long will Carpo be untill they dissapear from the top right corner, I want to know if I actually have a chance of getting this thing.

You have to do every single task, unless you use an Item Box (5 gold in the Premium Store) to mitigate the tasks

From the News tab, or first page of the forum: Carpo will leave on September 30th, 23:59!
