Ever watched the TLK1.5 credits? A few minutes into the credits, I was checking out the voice actors of the characters. If I remember correctly, they spelt Zazu wrong. They have it spelt as "Zasu" and then the voice actor for the one line that Zazu actually has in the movie. (They had a new voice actor since the second movie in 1998)
I just found it interesting that they would spell a character's name wrong.
Correct me if I'm wrong but I thought I remember seeing "Zasu".
