During the fight scene between Tom-Tom and Barnaby, at one point Tom-Tom is on top of Barnaby, then does a somersault over him, and we see him start to stand up in front of Barnaby. In the next shot, he is on top of Barnaby again (same position as before he flipped), and in the next he is standing up in front of Barnaby.
When Stannie rings Barnaby's doorbell at night, a light appears in Barnaby's upstairs window. The light source comes from the right, but Barnaby appears from the left, carrying a candle.
Barnaby and the Bogeymen invade Toyland by crossing a crocodile-filled river on a large raft. When the Wooden Soldiers drive them out of the city and back to the river, the raft is inexplicably missing - ensuring that the Bogeymen will not escape from the hungry crocodiles.
At about 01:15:54, the soldier visible on screen right vanishes into thin air. A clear editing of two shots error.
The three little pigs are in their nightgowns - like everyone else in Toy Land - when Stan and Ollie return with Tom Tom and Bo-Peep. When the three little pigs close the blinds to their houses when the bogeymen are attacking, two of them are shown with their regular clothes on. Eventually they are seen with their nightgowns again when Toy Land is fighting the bogeymen.
The wooden soldier, brought out as a demonstration model by Stannie and Ollie, blinks in one shot.
As the animated wooden soldiers are marching away, a new line of soldiers keep magically popping up in the rear.
Gaping seams and obvious padding on the Bogeymen costumes.
The swamp comes to within a few feet of the Toyland gates, but when the gates are opened dozens of Bogeymen are seen beyond them, presumably on solid ground. The Bogeyland caves can be seen at the far background.
Old King Cole offers fifty thousand guineas for Barnaby's capture, but the IOU Stannie gives Ollie for the purchase of his pee-wees is written as $1.48 in US dollars and cents.
