This mistress felt that she had to demonstrate how ruthless she was and that is why she took a toy and she shrunk it and then used her giantess feet to crush it and destroy it. The mistress wanted to gain control through fear and that is what she did as she projected herself as ruthless and cruel if she needed to be. Then she extended the guys she wanted to control an olive branch for them to support her or face the same fate as the toy she had crushed.
