Can somebody fill me in about what is "the fall"? I'm still having a little trouble comprehending this.
As far as what killed Mufasa, the fall would have at least broken Mufasa's backbone had the wildebeest stampede not been there, and by my estimates, he would have survived, but been paralyzed or something like that. It was the wildebeest stampede that killed him which finished the job.
Also, how come Scar isn't an option? I thought he killed Mufasa.
