With a flash, the lady disappears.
At first you think she just disappeared, then you heard her voice. "What did you do to me?! Why can't I move?!"
You look down at the corgi. He looks up at you, his nub tail wagging.
"I am going to call my lawyer this instant. Get me my phone!"
The corgi doesn't seem to be speaking, but the voice does seem to be coming from the corgi's direction. You kneel down and pet the corgi, causing his tail to wag more.
"What is that strange smell, and what is that thing moving above me? You better have some answers, buddy."
Moving above her? You look at the corgi's wagging tail. No, the keys couldn't have done that. Could they?
You look behind the corgi at his butt. Looks like a normal corgi butt as far as you know. "M'am?"
"Oh! There you are. What is going on? Wait, where are you going? Don't leave! Come back here!"
You ignore the lady's voice. As far as you can tell, somehow, the keys had turned the lady into a corgi's butt, though the only sign was the lady's voice coming from that location. Definitely got her out of the way, but opened up a variety of circumstances you did not want to consider. You figure taking the dog for a walk would help you clear your head so you could figure out what to do next.
