It is certainly not difficult to trace the roots of the Chinny, Chin, Chin Construction Co., the latest identification from our Toontown Field Guide. This window is featured on one of the buildings in Mickey's Tootown in Disneyland. The Silly Symphony The Three Little Pigs was released in 1933 and has long been considered a high water mark in the history of Disney animation. Central to the story was of course the building of houses, thus the casting of the three heroes as Toontown construction contractors.
Even more fun is that if you travel cross country to Walt Disney World in Florida, you will find Practical Pig and his brothers similarly referenced in Mickey's Toontown Fair at the Magic Kingdom. There, the Chinny, Chin, Chin Construction Co. has been contracted to do remodeling work on the kitchen in Mickey's country house. This is evidenced by blueprints that can be found on Mickey's kitchen table.
