Sam planted himself back to the platform, gathering up another burst of energy around one hand, ready to fire way before that thing got close enough for him to see the proverbial whites of its eyes. (There had to be a better saying for things that definitely didn't have eyes. Things that were unimportant, but much more pleasant to think about than the idea that those things might be smart.)

"I kind of want to take it down after we cross, but who am I kidding, what if those things can jump like the killer bunny in that one movie. We'd just be cornering ourselves worse."

...okay, now he was making himself think about more things he didn't want to think about, way to go.
