This is the first and only Winnie the Pooh film where Roo was voiced by a girl and not voiced by a boy. This would not happen again until Christopher Robin (2018).
Don't swing on a string / It's much too frail / The best kind of swing / Is a tigger's tail. Whee!
After Piglet, Pooh, and Rabbit lose Tigger in the mist, the surroundings of the sand pit on page 123 are the fallen tree and little trees. Then when Piglet, Pooh, and Rabbit return to the sand pit, there are more bigger trees and bushes within the pit's surroundings and there's a bigger tree where the fallen tree was.
