The new fiftywords theme @miniature-tiger for week 4 is "ZOO".
My submission is as follows (50 words, title not included).

When The Tables Were Turned

In fifty words:

The hippo was keeping them quiet.

"That’s the last one," the caracal turned the key.

"I’ve lost count," the Turkey vulture stretched a wing.

The Philippine tarsier found the challenge daunting:

"Do we now have to make labels for all of them?"

"One will do. They are all the same."
