Klick'it, Klick'its (n, click-it): man-sized insecticides that resemble praying mantises. Named after their language, which consists chiefly of 'Clicks' & 'Clacks', they consider the human spleen the ultimate delicacy.

The wrong way to communicate with a Klick'it:
Click-Clack (Spleen, now!)
What? You want my spleen? Over my dead body.
Click-Clack (Okay, dokey.)
Ahhh!

The right way to communicate with a Klick'it:
Click-Clack (Spleen, now! Note: by all accounts, this is their standard greeting.)
I'm sorry, I'm still using it.
Click-Clack (Spleen, now!)
But if you wait a moment or two, I'd be more than happy to part with it.

...time passes

Click-Clack (Just how much time is this going to take, anyhow? Note: Klick'its are not known for their patience.)
Just a moment. Hey, isn't that one of your friends?
Click-Clack ('Spleen, now!' says the newcomer.)
I'm sorry, I'd like to accommodate you, but I've already promised my spleen to another.
Click-Clack (That's right, his spleen is mine!)
Click-Clack (Oh, yeah!)
Click-Clack (Yeah!)

And during the ensuing scuffle, a smart space traveler will quietly make their departure.

Oh, and I guess I should mention, Klick'its tend to be solitary creatures, not being particularly big on sharing, if you know what I mean.
