Continuity mistake: In one scene, Rabbit picks three flowers. In the next shot, Rabbit gives all of the three flowers away and still has one for himself without ever having gone back to the bush to pick one more for himself.
After Winnie and Tigger try to distract Kanga by saying "is that a fish in that tree?", there is a new exterior shot of Piglet's house with some trees in the corners in the foreground. There is a fish in one of them.
