Okay, so the Yeti's rampage is abated temporarily, not by force of arms or the brilliance of science, but because he runs into a crying child and feels sad for it, so he stops rampaging for a minute. The Smart Daughter takes this opportunity to tut tut him for destroying part of Toronto; she does this while still in his hand, which is maybe less than smart of her.
The authorities are unimpressed, and summon their yellow police taxi cabs to arrest the Yeti.
