A humanized mouse along with humanized animal friends , go outside their houses to do the tiniest and no needed tasks.
I would say, Simile because this compares the feeling of seeing the machine to being stabbed by a dozen awls. Similes use like or as to compare two different objects, so that is what leads me to believe this. It cannot be a symbol, because that does not represent anything. It cannot be personification because it does not take a nonliving object and give it human features. I would say that's it a metaphor, but it uses as, so I firmly believe that it is a simile..
First get there attention.Ask them if they ever had the same feeling of it.Tell them something compared to you and it.Be specific but attention maker.But dont be too specific ,itll be a little boring and wont get attention.Hope that helped
