Story!
We have to get the animals now, so go to the butcher store and talk to your mother about every topic, she'll tell you that the animals come from Nika's family farm, but we don't know where is it.
Go to Nika's house and talk to her, select "I need to know where her Aunt's farm is", she'll give us some random riddle.
Following the riddle, go to the circus and talk to the clowns flags, first Casper, then Charlie and Casper again, they'll open the farm for you.
