Hmm I think they should explain these Circle of Life plotholes in a future episode, even children must be wondering these things
If I had to explain it somehow, I guess some parts of the Pridelands work much like an animal sanctuary, where animals don't need to worry at all about predators, and when one animal like the okapi enters these designated areas, they're protected by law. But those are just thoughts, as long as Disney doesn't explain it it's still weird xP

As for the episode itself, I quite liked it. Makucha is such an awesome new villain! I hope we'll get to see him again at some point. And the song, even though I'm not really into rap either, I still found it pretty good, at least they used guitar play in the background instead of a beatbox

I lost it at the zebra leader being offended because Makucha said the okapi was tastier than him. That was hillarious I love that zebra
