I'm not sure if anyone has already said this yet or had the same idea as me, but let's get started.

I know that first-gen leopons can be bred randomly with a 1% chance for your lioness to cheat on your main male. everybody knows that, but do you guys remember that one smug leopard flirting and hitting on lionesses? perhaps when you claim that lioness, and then breed it there's an extremely small chance of it going back with the leopard and breeding with him.. I've heard of something called a "dreamboat chance" and that crbs, posed lionesses, etc are only claimed because you're a dreamboat so that just might be one of the ways first gen 1 leopons are born, but it wouldn't make sense... I feel like there's a way higher chance if your main male has a really low impression level, because that would cause your lioness to think you're ugly and weird, so she goes to breed with the leopard. I think there's an even higher chance if your main male's impression is below average. because Ashkarn's (the NPC tiger that produces first gen tigons) impression level is average, so I'd suspect that the leopard's impression level is around the same. now I might be going WAYYY too into detail and you may think it's not that deep, but what if it is?

EDIT: when i say "higher chance" since I know it's an EXTREMELY low chance to get a first gen leopon, I mean there's a 0.9 higher chance of it happening.
