The flipping storybook pages which serve as scene transitions are almost all identical.
The storybook that opens at the beginning of the film has the title "Winnie the Pooh and the Honey Tree" (since it was created specifically for that short), but only reads "Winnie the Pooh" when it closes in the end.
When Pooh and Piglet are in Owl's house, and the table was sliding down with the tea cup almost about to hit Piglet, the cup was filled with tea. A few seconds later, when the cup falls onto Piglet's head, the cup is empty.
The last two chapters ("The First Snowfall Had Covered The Hundred Acre Wood" and "Christopher Robin and Pooh Come to the Enchanted Place and We Say Good-bye") are both "Chapter X".
Just before Tigger's first appearance, Pooh's door latch changes from a double bracket to a single bracket and pivot.
While Pooh is dreaming of heffalumps and woozles, watch very carefully as the two heffalumps dance in the honey, about halfway through, the honey starts flying up into the air and onto the feet of the dancers, a sure sign that the animation was reversed to make the sequence longer.
When Rabbit turns in his chair to try to avoid seeing Pooh stuck in his door, he quickly glances to his mirror while he says "Oh no, there it is again!" At this point, only Pooh in seen in the mirror's reflection, but not Rabbit.
When Tigger hides under the desk and asks Pooh if he's gone, the mirror shows Tigger's tail, but not Pooh.
When Pooh is on guard for creatures that Tigger told him about, he goes up to the mirror and tells him, "You go that way...and I'll go this way." When Pooh turns to his left, so does his reflection.
Christopher Robin counts down from four before Pooh uses the balloon to fly up the honey tree. This sequence is based on a chapter from the book "Winnie-the-Pooh", published in 1926. The concept of a countdown prior to a takeoff was introduced in the German silent film "Frau im Mond" ("Woman in the Moon"), released in 1929.
When Tigger is sadly walking away after being told he was promised never to bounce again, his snout is the same color as his fur in a few scenes.
The second time Tigger says, "Hello, I'm Tigger!", his nose turns darker red for a single frame.
When Pooh, Piglet and Rabbit are wincing as Tigger screams into the log, Piglet's scarf turns the same color as his bodysuit for a split second.
