Go back to Pupsville, then go to Dr. Potan's clinic. Talk to him, and he will tell you that he knows what herds he needs to use, and he wants Blackie to find them now.
Yellow Flower
You will memorise the smell of the yellow flower, and it is a mixture of two smells. You need to find both objects first, then go to Green Meadows and sniff out the yellow flower, which will later become a sunflower if you find it for a collection. Take it back to Dr. Potan, and he will tell you that he also needs a herb called the Blue Flower, and he asked the nurse, Francis the Bichon Frise, to get it, but she should have been back by now. He asks you to find out if why she's taking so long. You need to go back outside the clinic.
Brave Fruit for Francis
When outside, you will see that three of the Victory Gang dogs, Clark, Will and Camu, are throwing tomatoes at Francis. She faints at the sight, but luckily Blackie growls at the three bullies and they leave. After all that, Francis wakes up. She tells you about the victory gang dogs and their pranks, but she says that they aren't really to blame, it's her weakness. Although she is a nurse, she cannot stand the sight of blood. Apparently she was fine at first but after a while it got really bad and she faints at the sight of red! She is too nervous to tell you the smell of the blue flower, though, but she has heard of a fruit that has the power to make dogs braver.
It is called the Brave Fruit, and it grows in Green Meadows, and Francis thinks that if she eats the Brave Fruit, she'll have the confidence to tell you what the Blue Flower smells like. So, you need to go to Green Meadows, and then sniff around near the broken bridge. It's a bit to the right. Find it, then take it back to Francis. She feels a little braver, and can now tell you the smell of the Blue Flower.
Broken Axe
Blackie memorises the smell of the Blue Flower, and francis tells you that it is in the Treely Woods near the entrance to Zoomy Lake. To get to treely woods, you need to go through Green Meadows along the path, watch out for the Warthog and the Bear, and you will come to Treely Woods. Go along the path slightly and you will come to a bridge. After going across it go along the left path and you will see that there is a large log blocking the path to Zoomy Lake. A Boxer Dog will be standing next to it with a question mark over his head. Speak to him, and he will tell you that he will cut the log, but his axe handle is broken. A gorilla in Treely Woods had an axe handle, and he will tell you qive you directions. Basically, you have to go back across the bridge, turn left and go past Eve the Datchund who is standing guard over the path to Pupsville (it's not finished yet) and you will come to the end of the path. To your right will be Obaba's house and to the left will be a gorilla. Wait patiently untill the gorilla falls asleep but before then don't go too close or he'll see you. When he falls asleep, go up to him and bark or howl, and he will drop the axe handle. Take it back to the Boxer, and he will chop the log.
Before long, the log is no longer blocking the path and you may pass. The Boxer who helped you will go home because his back is starting to act up.
The Blue Flower
Go along the path slightly and start sniffing when you come to an area just off the path, where there are lots of flowers. You should find the Blue Flower here, and once you've got it, take it back to Dr. Potan in Pupsville.
He will thank you and say that you should rest up. When you get outside, Petasi will go 'Hmm?'. Blackie wonders what the matter is. Petasi replies 'Oh, I thought I just felt a little pain in my stomach. Oh, it's gone' than he says that you stould rest up, like Dr. Potan said. So, go back to your house, go to the bed, and select 'sleep'.
Curing an Anc's Stomach Ache
When you wake up, Petasi is rolling around on the floor in pain. He tells you that his stomach hurts and that it hurts even to talk. He cries out; 'A Doctor, get me a Doctor!' And so your instincts say go to Dr. Potan.
However, if you go to the clinic and talk to him, he will tell you that he doesn't really believe in ancs, but Alex, a Black Labrador like Blackie, likes stories like that, so you should go and see him. He tells you that Alex lives in the house shaped like a book. So, go out of Dr. Potan's clinic, and you can find Alex in his house (or more like a tent) which is behind Amalia's house, because Alex and Amalia are brother and sister.
Talk to Alex, and he will ask you what's wrong. Petasi tries to explain that he has a stomach ache, but Alex can't hear him and says that he can't hellp you if you remain silent like this. Petasi realises that there are two kind of dog in this world; those that can see ancs and those that can't. Petasi asks Blackie to explain to Alex what the problem is. He tells Alex, but Alex doesn't really believe in ancs either, but he has read about them. He says that you should go and see Obaba, a Shih Tzu who is also a healer. But apparently, her ways of treating once made a dog fatally worse, but you don't have much other choice of doctors to go to. She lives in Treely Woods, and you can now get there through the shortcut which was blocked earlier, but they have now finished the road. Alex will give you directions. So, go back to the town centre and go along the path to the right of the café, past Tom the Papillion who was blocking the way before, and go to Treely Woods. Turn left and go along the path, go through an arch and you will be by Obaba's house. Go inside, and you will meet Obaba and talk to her.
Ashes from the Fireplace
Obaba asks what the problem is. She cannot see Petasi, but she can somehow sense he is there. To cure his stomach ache, she needs some Ashes from the Fireplace. She asks if you have a fireplace at home, and you can get the Ashes from the Fireplace there. She tells you what the ashes smell like. So, go out of Obaba's house and back along the path. Go path Eve and go through to Pupsville, and then go to your house. Sniff around the fireplace and you should find the ashes. Next, go back to Treely Woods and to Obaba's house.
Petasi asks Obaba if she can hurry up and make some medacine with the ashes, but she tells him that she is not going to make medicine with them, they are going to help her see Petasi. She rubs some of the ashes in her eye (sounds painful) and she can see Petasi. She says a few random words and then howls... Petasi's stomach ache is gone! Obaba tells you that she doesn't have many customers any more, because of one dog she couldn't cure. 'It was that doctors... best friend.'
Obaba says that you should rest up (again) so go back to your house and go to sleep.
