==Purpose of the "Upstate Four" reference== 

 I've added this Cartoon Brew article  "The Upstate Four: An Interview with Fran and Will Krause" by Amid Amidi as a reference for the following sentence (in the "Production" section: 

 His brother Will voiced the monkey and was the only other actor in the film. 

 Although this article from Cartoon Brew doesn't actually mention Mister Smile anywhere, I'm using it as a reference to show that Will Krause is Fran's brother.
