During the tutorial with Black: Go next to the house that is near to her.
After the tutorial: Go to the forest. In the right road (The one with the taming spot) there is a entrance to a carrots lair
where is the forest that you speak of, I'm still stuck in the farm and there's no forest I can acces
Are you inside Black's Barn?
When she tells you to find carrots for the first taming, you can find them on the floor, next to the house where Black uses to be.
Try pressing TAB key, it should turn Nishy towards the carrots spot and create a blue beam at that spot
