"So they do me," agreed Cap'n Bill.

"But the octopi are not very bad," said the Princess, "and we get along with them much better than we do with their cousins, the sea devils."

"Oh. Are the sea devils their cousins?" asked Trot.

"Yes, and they are the only creatures of the ocean which we greatly fear," replied Aquareine. "I hope we shall meet none today, for we are going near to the dismal caverns where they live."

"What are the sea devils like, ma'am?" inquired Cap'n Bill a little uneasily.

"Something like the octopus you just saw, only much larger and of a bright scarlet color, striped with black," answered the Queen. "They are very fierce and terrible creatures and nearly as much dreaded by the inhabitants of the ocean as is Zog, and nearly as powerful as King Anko himself."

"Zog! Who is Zog?" questioned the girl. "I haven't heard of him before now."

"We do not like to mention Zog's name," responded the Queen in a low voice. "He is the wicked genius of the sea, and a magician of great power."

"What's he like?" asked Cap'n Bill.

"He is a dreadful creature, part fish, part man, part beast and part serpent. Centuries ago they cast him off the earth into the sea, where he has caused much trouble. Once he waged a terrible war against King Anko, but the sea serpent finally conquered Zog and drove the magician into his castle, where he now stays shut up. For if ever Anko catches the monster outside of his enchanted castle, he will kill him, and Zog knows that very well."
