Strange thing about TLK 1&2

Now,I think this will sound a bit crazy and stupid,but I'll still give it a try...
So,everybody remembers the Just Can't Wait To Be King scene where all animals were singing,at the end of the song.I noticed alligators and crocodiles singing too.So,now I'll tell what's wrong.
In Simba's Pride,probably the same alligators(or crocodiles)attacked Kiara and Kovu.So now,don't they remember the song?That Kiara was Simba's,king's,daughter?
I know that this article may appear as pointless,but this just didn't fit for me.Did they forgot that they were singing how good of a king Simba will be,and now they want to kill his daughter?
