Dr. Horace Pythagoras is a famous naturalist who is also Joni's uncle. He is called Dr. Pythagoras by most people, although Joni usually calls him Uncle Horace.


Dr. Pythagoras has short, neatly combed orange hair, an orange mustache, a short orange beard, and black eyebrows. He wears round golden-rimmed glasses, a tan button-up shirt over a white undershirt, brown shorts, white socks and dark brown boots. In the book The ClueFinders: The Mystery of Microsneezia, Dr. Pythagoras is described as having brown hair rather than orange.


Dr. Pythagoras is a confident and capable scientist. He is able to remain calm in most situations and prefers to look for logical answers to problems rather than rely on superstitions or myths. Dr. Pythagoras has been shown to be generally kind and understanding, such as when he sympathized with S.N.A.I.L.L. and the local Microsneezians in The ClueFinders: The Mystery of Microsneezia. He is close to his niece, Joni, and the two of them go on a lot of adventures together.

The ClueFinders: The Mystery of MicrosneeziaEdit

Dr. Pythagoras goes an expedition to Microsneezia and discovers a rare plant called the vegemecium, but then he mysteriously goes missing. He sends a distress signal to the ClueFinders, and they go to the island to search for him. While trying to assist the ClueFinders, LapTrap runs into S.N.A.I.L.L., an identical-looking but aggressive version of LapTrap, who was considered a failed project and was banished to Microsneezia by the military after Dr. Pythagoras suggested it as a kinder alternative to destroying him. S.N.A.I.L.L. reveals that he is responsible for Dr. Pythagoras' abduction, since he seeks revenge for Dr. Pythagoras banishing him to the island, and then he damages LapTrap. After S.N.A.I.L.L. manipulates the local Microsneezians into trapping the ClueFinders in a cave, the kids reunite with Dr. Pythagoras in a laboratory room in of the cave. Dr. Pythagoras fixed LapTrap, who was captured and thrown into the cave as well. Since Dr. Pythagoras seems to be immune to the various irritating plants and animals of Microsneezia, the Microsneezians have ordered him to find a source for the immunity. With the ClueFinders' help, Dr. Pythagoras is able to isolate the source, which turns out to be bubblegum. He presents his findings to the Microsneezians, and the mayor has S.N.A.I.L.L. locked up. However, the Microsneezians then tell the ClueFinders to locate a quarry of liquid bubblegum on the island, and keep Dr. Pythagoras hostage a while longer as leverage. After the ClueFinders spread the bubblegum throughout the island, Dr. Pythagoras is let go, and he forgives the Microsneezians for imprisoning him. S.N.A.I.L.L., who had gotten free, collapses near them after running out of power. The ClueFinders are very reluctant to help S.N.A.I.L.L., but Dr. Pythagoras is convinced that he could be changed by extracting the microchip responsible for his aggressive attitude. After Dr. Pythagoras does this, S.N.A.I.L.L.'s personality changes to cheerful, helpful, and loyal. Upon returning home with the ClueFinders, Dr. Pythagoras publishes his findings about the vegemecium plant in a scientific journal.
