Hmmm. Well, let's see. If it's a sequel...
The hyenas or some other animal herd with an axe to grind have somehow taken over, and this time they've taken out all the possible heirs. None of the other animals want to attempt to take back the pride lands, out of fear of death, until a wild turkey named Dandays is accidentally transported there by some means—probably a zoo or some sort of animal rescue organization.
Dandays is an outsider and so neither side really trusts him, but throughout the movie he's able to befriend some of the smaller animals and convince them that this can't go on forever. Maybe Pumba and Timon or someone we already know.
There's no way this plot has been building so the fact you just whipped all that up is impressive. Feel like I need popcorn and 3D glasses.
