Thanks and one more question:

*On the low end*, a three-pack of agile, pint-sized, carnivores.

Again I'm in need of your indispensable help:

is it simply the end of somewhere, which is lower, that is a location?

because later they say:
"Towering above them..."

Thanks a lot

Almost certainly a reference to their small size. An interesting choice of words, though. "On the low end" is often used to describe those items that are cheapest on a price list or menu. The metaphor works if my guess is right.

"But no one's *wired to stay afraid* for too long, including Pod"

somehow I don't understand this sentence. I know that wired is excited or nervous but what does he want to say exactly?
Thanks a lot

Wired = hardwired? Pod can choose whether to continue to be afraid.
