I'll tell you in a word or two why the King of the Goat Frogs has a lump on his side. A long time ago, back in the ancient world, the goat frogs may have had a king, but people heard about it by hearsay, but they didn't know which one was king, because they were all the same.
One day a king (a real king) announced that he would give a hundred forints to anyone who would show him the King of the Goat Frogs. There was only one boy in the whole country who knew the King of the Goat Frogs, and he led the King to the lake and showed him:
- Ihol, my king, this is the king of the goat frogs.
Then the king of the goat frogs spoke:
- Brekeke, this boy is right, I am the king of goat frogs.
So the king paid the boy the hundred forints at once, but the boy had only one shirt and no other clothes, and he didn't know where to put the hundred forints. The king of the goat frogs saw that the boy did not know what to do with his money, so he told him:
- Give it to me, I'll hide it well, and if you need it, I'll give it back.
The boy gave him the money, the frog swallowed it, but it was so stuck in his stomach that he could neither give it back nor digest it, and the hundred pence left a big lump on his side.
Since then, it's easy to get to know the king of goat frogs because he has a hump on his side.
