Mancandy - stop legs stretching

Hi, I’m determined to start animating with Mancandy but I still find him a mystery. I’ve managed to stop the arms from stretching but how do you stop the legs from doing so (when you lift Mancandy by the hip)- I thought the legs would be the same as the arms – there seems to be tons of bones in the legs but I can’t switch off the stretch feature - anyone know how?
