Swamptown Pudding Quest
After talking to the man in the bar you find out that a strange organization is hiding the gold slime somewhere. You go and talk to the old man in the society and ask him about it. He tells you hell show you if you kill 100 green puddings for him.
After doing so you come back and talk to the man. He lets you into the society which has some books, people, and then sitting at a table is a golden pudding. You talk to him and he tells you that puddings used to be nice creatures, and humans used to keep them as pets. He tells you that they used to live together in a society allied with the humans and he was their king. But then an evil pudding began telling lies and saying that humans were killing them. So he lead a rebellion, took him out of power, and he just barely got away. Now they attack the humans, and they have no choice but to fight back. You have to go defeat the king pudding in the pudding caves. He is a huge black pudding which breaks 5 times before being defeated. Succeed and you get a gralat reward from the gold pudding, access to the society ( maybe put something cool in there like checkers or something), and a pet green pudding for your house which isn't hostile.
