Fat Cakes World Headquarters

Fat Cakes World Headquarters is the main headquarters and factory that makes and produces Fat Cakes and Fat Shakes. It is located in Canada. It is also mentioned that over 65% of the world's Fat Cakes are produced there.

It was shown in the episode iToe Fat Cakes when Spencer, Freddie, and Gibby took Sam there for a tour of the factory.

It is also noted that the fat cake factory fills 95,000 fat cakes with cream every day.

The building is probably in British Columbia because that is the only Canadian province that Washington (where Seattle is) borders.
