He was at the head of Princess Ozma's Royal Athletic College, and so that the students would not have to study and so lose much time that could be devoted to athletic sports, such as football, baseball and the like, Professor Wogglebug had invented the famous Educational Pills.

If one of the college students took a Geography Pill after breakfast, he knew his geography lesson in an instant; if he took a Spelling Pill he at once knew his spelling lesson, and an Arithmetic Pill enabled the student to do any kind of sum without having to think about it.
These useful pills made the college very popular and taught the boys and girls of Oz their lessons in the easiest possible way.

In spite of this, Professor Wogglebug was not a favorite outside his college, for he was very conceited and admired himself so much and displayed his cleverness and learning so constantly, that no one cared to associate with him.

Ozma found him of value in her councils, nevertheless.
Perhaps the most splendidly dressed of all those present was a great frog as large as a man, called the Frogman, who was noted for his wise sayings.

He had come to the Emerald City from the Yip Country of Oz and was a guest of honor.
