Continuity: They mention that the goose has hatched out 7 goslings. They say there were 8 eggs and one didn't hatch. The one egg is given to Templeton, and it is later smashed open. Later that night as they're going to sleep, the mother goose has 7 goslings under her, but then then it shows Jeffrey (one of the goslings) sleeping with Wilbur. Seems they had an extra gosling with the mother.
