There should be a mine that once dropped turns into a cargo with a randomized name, which blows up 3 seconds after it's picked up.
Why?

Pie rat: I'm goin to liberate yer cargo!
Trader: Okay! here you go, please dont shoot!
*Pie rat picks up cargo*
*BOOM!*
Pie Rat: Yarrrrr! Ya got me!

Or you can make it drop cargo such as "Itani eating virus", "Serco rampaging nanites", for those who forget to care to look at what the item is.

and a Trojan Rabbit and a Trojan Badger...

:D

technically, wouldnt a trojan horse be a big ship that you could dock in, and take you into enemy territory without harm?

then you could pop out and kill the romans?`

Trojans != Romans.

Haha I like how in both these threads they have a scripted example :)

No you want to kill the Trojans not the Romans, which have nothing to do in here.
