Patalliro the 8th

The ten-year-old king of Malynera. He is a child genius, having finished both his lower and higher levels of education. He is a master of disguise. He is an inventor and a scientist. He can travel through time. He also has the emotional maturity of a two-year-old. His escapades and strange games are well-known to his caretakers, who often have a hard time keeping up with him. Perhaps his most enduring gift to posterity is the "Cock Robin Dance".
