Synopsis
A man apprenticed his son to a master-thief, who said he should pay nothing for the education, but if he could not recognize him, then he would have to pay. When he returned after a year, a dwarf advised him to bring bread, and that the little bird peeping from the basket he finds there is his son. By this means, he gets his son back.
The son changes himself to a dog, his father sells him, and the son escapes. The son then changed himself to a horse, warning his father not to sell him with the bridle, his father sells him to the master-thief without taking off the bridle. When the master-thief stables him, he asks the maid to take off the bridle, and she is so surprised that he talks that she does so. The son and the master-thief interchange a transformation chase — first sparrows, then fish — with throwing lots, and the son ends it by turning into a fox when the master is a cock, and biting its head off.
