Revealing mistake: Laying in bed asleep, Lulu has a sucker swinging on a string to and from her mouth as she snores. When we first see her, after the sucker leaves her mouth the first time, her hair has a glitch. For a few frames, one loop of her hair vanishes, and then comes back. This repeats each time the sucker moves away from her. (00:00:45)
Audio problem: As Lulu drops from the moon beam onto some books, the school house says "Or would you rather be a mule?" It pauses for a moment, and then you hear the school house begin singing about a mule as the camera cuts to a close up of the mule drawing in a book. But a split second before the cut, the school house begins his singing, and gets a couple words in before the camera cut. However you can see the school house’s mouth is not moving at this point. (00:04:05)
Continuity mistake: Lulu dashes to the bathroom after getting out of bed to go brush her teeth. In the side shot as she grabs her toothbrush, it is orange. But when it cuts to an over the shoulder view of her putting toothpaste on it, suddenly it is dark green. (00:01:15)
Continuity mistake: After waking up, Lulu's clothes are suspended from the ceiling and she leaps from the bed down into them, getting them perfectly on her in an instant and then runs off. Her hat is not amongst the items, and as she runs off screen you see that she has nothing on her head. But the shot changes to her running directly to the bathroom, and suddenly her little red hat is on her head. (00:01:10)
Other mistake: When Lulu is looking at herself in a three sided mirror as a monkey, the reflections do not match up with her position of her hands. Most noticeably with the reflection on the right side. (00:05:40)
Continuity mistake: In the dream, the school house asks Lulu if she'd rather be a pig and pulls up a blackboard with the word PIG written on it. There is a stick of chalk at the bottom of the board to the right. When it cuts to a close up of the blackboard, the chalk suddenly moves closer to the center of the board and is almost under the word PIG. (00:04:40)
Continuity mistake: As Lulu’s shoulder angle tells her that she will turn into a mule if she doesn't go to school, the shading on Lulu’s chin suddenly changes and gets darker, like a shadow just appeared from nowhere. (00:02:55)
Audio problem: During the dream sequence in the song, Lulu begins swinging from three different stars depicting 3 different faces of celebrities at the time in black and white that have their lips moving with the song as they sing. However their lips are off sync with the lyrics by a little bit and are moving slower. (00:04:25)
Continuity mistake: The school house says "Or would you rather be a fish?" as Lulu plummets into the water around the letter blocks the school house is sitting on. She lands in the water next to two blocks reading F and C, the F block being a light blue and the C block being a slightly darker blue. But when it cuts to a close up of her in the water, both blocks are suddenly a very dark blue. (00:05:15)
Continuity mistake: When the school house picks up a blackboard marked PIG, there are two of the giant letter blocks behind it. A red one with O and a dark purplish blue one where the letter is hidden by the walkway. But when the blackboard is knocked down and turns into a puddle of black mud, the blocks behind it are now a white block with the letter N and a light blue block with the letter L. (00:05:00)
Revealing mistake: As Lulu is pulling her fishing pole out of the school steps, you see if you watch closely that the pole actually passes through the concrete of the steps rather than her lifting it over. (00:02:00)
Continuity mistake: As Lulu is racing up to the school, you see the brick base of the school house and that the bricks are a dark red color. It then cuts to a closer angle as she is about to pull her fishing pole out of the steps and suddenly the bricks are now a light grey. Also in the same shots, you see first that the tree's shadow is lay across the walkway in front of the steps. But in the close up the shadow is nowhere to be seen. (00:01:55)
Continuity mistake: Lulu slides down the banister onto a stool and slides across the floor to the table for her breakfast. She gets to the table and looks at her selection for a moment, the camera still looking from the side and her hands at her sides. It cuts to a close up from in front of her and suddenly her hands are up on the table. Also the cups on the table change shape, from being more conical towards the bottom, to perfect cylinders. (00:01:30)
Continuity mistake: A full school day passes from when Lulu is first at school to get her fishing pole and to when she returns after awakening from being knocked out. It even looks darker from time passing. But the shadow of the tree is exactly the same, when the moving of the sun would have changed that. (00:01:55 - 00:07:10)
Continuity mistake: When Lulu lands on the book, before the drawing of a donkey attacks her, there is a wooden sign hanging that says school. The edges are quite jagged. After a bit of singing from the school house, another shot of the same sign shows it much less jagged. The style of the letters also change as well, and the metal part of the sign holding the sign to the post. (00:04:05 - 00:05:45)
Continuity mistake: Lulu gets out of bed and races to the bathroom to "Brush her teeth." She picks up a tube of toothpaste and a toothbrush, then proceeds to brush her reflection's teeth in the mirror. She does not set down the toothpaste, and when the angle changes as she washes her face, the toothpaste has vanished, not in her hand, not on the sink. (00:01:20)
Continuity mistake: As the episode starts, Lulu is snoring in bed. The purple head board of her bed is in the light in such a way that it is diagonally lit up from the top left to bottom right. When the angle changes as she gets up, the lighting has flipped so the bottom part is lit rather than the top. There is also a window that suddenly appears in the wall by her bed that was not there in the previous shot. (00:01:05)
Chosen answer: She writes "I'll never play hooky again."
