The robber is lying on the ground, breathing heavily.
'Uhh... you people... how are you okay with this...' — he says slowly, as if he has trouble moving his lips.
You see his skin become smooth and shiny. It's all peachy and rubbery-looking.
The guy's legs spread apart, exposing his crotch. He tries to move them back but they spring open again.
'You are not going anywhere now, mister!'
The wand-wielding girl finally manages to push her way through the crowd. Even on tall platforms, she is a bit shorter than some of the people here. Same as you, though; you two seem to be the same height.
She hands the purse to the lady in heavy rubber dress.
You turn your gaze back to the guy and gasp in surprise. He's now almost fully turned. Latex body, painted eyes, round mouth, huge inflatable boobs and cartoonish proportions all indicate that he is nothing more than a sex toy.
The witch girl touches him with her wand again. All his clothing disappears, revealing plastic holes where his dick and anus used to be.
'A few month like this will teach you a lesson' — the girl says, picking the doll up and and pulling out the valve art its belly-button. She hugs the toy, making it deflate faster as it squeaks rubbing against her dress. You're just a few steps away from her and you're finally able to see what it says on her hair accessory:
PUBLIC ORDER ENFORCEMENT
The crowd is gone now; they probably just wanted to see the transformation. Thus, the magical girl looks at you just standing there.
'Hey, I know you!'
