 While the tricking of a tortoise was the most popular method in Bulgarian mythology, in Dalmatia the legend refers to snakes, and among Serbs another version involves the locking of young hedgehogs in a box for their mother to unlock.In Serbia, one would also have to be quick to take the raskovnik, as the hedgehog would swallow it after use.In any case, turtles, snakes and hedgehogs are all animals with chthonic characteristics which were often variously associated with the underworld in South Slavic tradition.
