Prisoner children are afraid of the color blue, rustling leaves and cellphone ring tones

Cellar monster Josef Fritzl's children are afraid of the colour blue, rustling leaves and moving traffic after spending their entire lives underground, it was revealed today.


The imprisoned pair - Stefan, 18, and five-year-old Felix - face up to eight years of intensive therapy to recover from their sex dungeon ordeal and adapt to modern life.


Doctors have already built a windowless chamber for them to retreat to when coping with the outside world becomes too much, it was revealed today.
