The Dog Island/The Disappearing Doctor

When you wake up, go to the centre of the village and you will see Francis there with a question mark above her head. Talk to Francis and she'll tell you what her problem is.

Doctor gone Walkies
Francis will tell you that every month, on the same day, Dr. Potan goes out somewhere without telling anyone where he's going. She asks if you can find out and says that someone saw him heading to Zoomy Lake. Don't go through the shortcut to Treely woods, because Petasi will say that he doesn't think Dr. Potan went through there. Instead, go through the arch to Green Meadows. You will see Dr. Potan walking along the path. Go through Green Meadows and then to Treely Woods.

You will see Dr. Potan go across the bridge and then along the path to Zoomy Lake. Go to Zoomy Lake and Petasi will say that you've got to swim to get any further. Swimming is just like walking, except you cannot howl in the water. You need to go down to the beach, then get to the large island in the centre of the lake. There are some steps leading to it, but watch out for the crocodiles in the water. Get to the steps and climb up them, and you will see Dr. Potan. Go near him to find out what the problem is.

Dr. Potan is standing near his friend's grave. He tells you what happened. He says that his friend got sick, and he was trying to make her better, but Obaba told him that his medicine would only make her worse. However, he ignored Obaba, and so his friend died. Now every month he goes to Zoomy Lake to see his friend's grave, and he thinks that she's annoyed that he let his pride get in the way, and also that he keeps looking back to the past. Blaxckie goes back to Pupsville and tells Francis.

Francis thanks you, and tells you that there was someone with a strange hat looking for you. Petasi wonders if it was Yi Lu.
