Pérák, the Spring Man, was an urban legend originating from which country?

Pérák, the Spring Man, was an urban legend originating from the Czechoslovakian city of Prague during the German occupation of Czechoslovakia in the midst of World War II. In the decades following the war, Pérák has also been portrayed as a Czech superhero.

"The Springer" was said to leap out from shadowy alleys and startle passers-by. Oral tradition suggests that some of Pérák's leaps were of an extraordinary magnitude, including the act of jumping over train carriages, similar to England's Spring-heeled Jack.
