ok how this works each day on the calendar day has a theme and your adopt will be made based on that theme.
you can have a sort of say in what kind of creature you get there will be a list of specifics you can pick a little farther down.
i have put in 4 free days in and if you pick that day you get it free you won't know till you are about to pay
Each is going to be $2.50-$5.00
you pick the price the more the better the adopt/more effort and details.
your adopt will most likely be posted on the day you pick though i can't guarantee it on the exact day.
