When I did the Key's to the Kingdom tour last October I think I got some insight into why he isn't just right or as right as to what we are used to.
When we were in the Hall of President and they discussed the individual who did all the presidents, pirates etc.... The name escapes me but she talked about him several times. He retired many years ago but well he just kept working even redoing some of the Pirates.
Although it wasn't known which President would be elected yet they were already starting prototypes. He had been working closely with an apprentice for many years teaching her all of his tricks. I then believe that our guide told us that this would be the first solo one this person worked. I could be wrong but I remember thinking how exciting and scary it must be to have to capture a President.
