Lady Asmodina did not have much to do and she wanted to pass time whichever way she could. That is why she opted to crush the toys with her high heels. She took some of the toys and she trampled them with her boots and she stomped on them. By the time she was done with them, she had destroyed them. But she had passed a lot of time as she did it.
Lady Asmodina was bored and she wanted to do something to keep herself occupied. So she chose to crush toys. She loves to destroy things and to smash them so it was not hard for her to crush toys cars. She had found them in her garage and she did not care who they belonged to. The mistress just destroyed them as she had nothing else to do with them.
