I think it would be a good idea to be able to receive a skill gain for your male lion while roaming around and they get into a fight. For example;
Elephant; +1 str or sta
Lion; +1 str or sma
Hyena; +1 sma or spd
Cheetah; +1 spd or agi
Croc; +1 sma or skills
etc.

But with each fight there's only about a 20% chance(or less) to even gain a skill, since we already receive experience points, impression progress and silver beetles.
