Nice work! Best cliffhanger I've seen so far, I did want to see where it went.

There is a good start here that I think more on the story back-end development would have helped, but this line "Like a skilled monkey, Rheinos swiftly used the knives to create new footholds," while it sounds good on reflection it now has me distrustful of going to the zoo :)

I just got invested when it stopped. It was going really well though. 

I have mixed feeling about this entry. From one side, it clearly follows the theme and is not just "oh no, our plan failed" but more of a "we were asked one thing but we end up doing something else because of it". On the other side, there are the dialogues which, to me, sound a bit dry. I feel like a lot of emphasis was put on those, so it's a bit of a pity. But overall, good job!

Great use of dialogue and action, not wasting any words, it really let the story flow. There's a tightness to your prose, that keeps the eye darting across the page. That was a really fun boots on the ground story.

I enjoyed the story. Written well with cool characters.
