Somebody trained their creature to throw fireballs at the almost everything (enemies I suppose) and then relieve himself on the corpses…to quote:

The most terrible warrior I have heard of is a creature named Burn. Because he likes to burn things. At the moment he relieves himself on the corpse of his slain foes. Horrible.

Wow…think about that…first off you have to teach your creature to throw fireballs (takes a bit of time).

I can see the training program. Oh…my creature needs to relieve itself…ok…where’s an enemy…ok…found an enemy…ok…burn the enemy…done…ok…now it can relieve itself…no no…not against the rock or in a field but over there…where you burnt them.

Of course…the creature will link the two together…so that when it wants to defecate it will throw fireballs at an enemy and then run over and do its business.

There’s also a simple solution to the problem of making the creature want to relieve itself almost all the time. Since the AI is complex you can accentuate certain desires. For instance…if the creature wants to do its business then you reward it and it will want to do its business more often.
