The first time I ran into the smug leopard, my first thought was "why on earth would I attack him. Please come back to my cave and live there forever. My king is a sound sleeper, he probably won't even hear you creeping on his girls."

And that gave me an idea, how the player's agenda (get very rare valuable cubs from this guy) would normally be at odds with the kings' (protect his ladies) and the leopards' (be a smug bastard.)

So what if, when following him, there was a rare chance you would follow him to your own pride instead of an NCL?
When you get there, you could either attack him or invite him to stay a little while.
When he stays, the common outcome would be neutral or even negative.
For example, he embarrasses your king in front of his ladies in some way causing you to loose -1% impression or he steals a 20 SB and runs. The rare and "good" outcome for this event would be a male leopard decor, maybe along the lines of the "adoring" stuff? Just a sly companion to put on your lionesses.

To be clear, there would be NO increased chance of 'pon cubs if he visits. This is to poke fun at that idea, not to actually allow it.
It's just for laughs and the best possible reward would be apparel.

(Also, sorry if this is in the wrong area. It's a suggestion for an existing encounter that adds a decor. I have no idea where it would be best to put this.)
