Go into SOV as soon as you get to this level, because in the small stretch of road leading back to the Village Houses are three purple scents. Collecting all the purple scents on this level is relatively easy, because most of them are in the road, along the path going up the hill, and behind the supermarket. Collect them all, and a bone will appear in the dog bowl. If you go through the tunnel near the butchers shop, you will find a garden with low walls surrounding it on all sides, so you have to jump into it if you want to get inside. That may come in handy later. Behind the garden, there is a violet scent. It's easier to start getting the other ones if you collect it running away from the tunnel. The next two will be infront of you, and one will be in the garden with low walls. This wasn't the reason it would come in handy, though. If you are facing away from the building which the garden is behind, go through the alleyway on the right side, and you will find two more scents. The rest are dotted around the road, including two near the flowerbed, one near each of the trees, and one by the path going up the hill. When you've collected all twelve, another bone will appear in the dog bowl.
If you go into the supermarket and talk to the lady at the till, she will say she has a bone for you, but you can't have it, and then she tells you to beat it before she looses her temper. You can talk to her more than once, but she will always say the same thing. To get the bone, go back out onto the road, and find the eight green scents. Then, you will be doing a race with the dog catcher's Doberman (yikes!) The race goes along the pavement, through the smallest alleyway, round the garden with low walls, trough the tunnel, up the path going up the hill, over the bridge, down the steps, and goes across the finishing line. The Doberman is pretty fast, so he shouldn't be too far away from the supermarket if you beat him. Once you have taken control of him, go into the supermarket. The Doberman will bark twice, then growl, and the lady will give him the bone to make him go away. He will take the bone to Jake, and then you can eat it.
