What does Sugarcandy mean in Animal Farm?
Moses, the raven, represents organized religion, and tells stories about a Heaven-like place called Sugarcandy Mountain. His views, that reward is guaranteed to every creature regardless of their work in life, goes contrary to Old Major's views of revolution and sacrifice; his stories are in opposition to Animalism, and to Napoleon's desire for personal power:
...a mysterious country called Sugarcandy Mountain, to which all animals went when they died... In Sugarcandy Mountain it was Sunday seven days a week, clover was in season all the year round, and lump sugar and linseed cake grew on the hedges.
(Orwell, Animal Farm, msxnet.org)
Although his stories are no more true than the promises of Old Major's philosophy, some of the animals cling to the hope that they will have an easier time after their death. Unfortunately, this makes them more susceptible to Napoleon's rule, as they think that even if they don't get their reward in this life, they will get it in the next; the truth is that there is no Sugarcandy Mountain, but Napoleon's dictatorship keeps them hungry and cold regardless.
