The Super Mario Bros. Super Show! (1989) - 26 mistakes in "Robo Koopa"

Continuity: Near the end of the episode, when Koopa is tricked into pushing the ejector seat button, Bunsun has disappeared beside Dr. Nerdnik.

Plot hole: Near the end, Robo Koopa sets down Dr. Nerdnik after he had just captured and held him hostage. Why would he do that?

Continuity: Koopa manages to take Toad and the Princess hostage by surrounding them in electric force fields so they can't move. These force fields disappear when Koopa starts chasing Mario, Luigi, Bunsun and Dr. Nerdnik.

Continuity: When the brothers, Toad and the Princess are dashing away from Koopa, there is a shot with the four of them running offscreen. Notice the background as the camera pans to Koopa. The next shot shows a very different background.

Other: In a wide shot of the Mario brothers dashing from Koopa, they run over an open hole, though nobody falls into it.

Continuity: When Luigi crawls out of the remains of the Plumbernator warsuit, his face is still in the unit of where it was when he was in it, even though he's outside of it right now.

Other: Mario has vanished when Luigi says "Koopa was scary enough when he was a reptile."

Other: Near the end, Dr. Nerdnik tricks Robo Koopa into pushing the red ejector seat button on his suit by saying it will run out of fuel unless he pushes the button. He pushes one of the white buttons, yet he ejects anyway.

Continuity: During the fight, when the Plumbinator starts firing eggs at Koopa, for a brief time the buttons on the left side of Koopa have vanished.

Continuity: At the start of the fight between Robo Koopa and the Plumbinator, Koopa fires a black bomb. The number of bombs in this sequence keeps changing, from 1 when he fires it, then 3, then 2 when the Plumbinator sends the bombs back to Koopa, then 3 again, and finally 2 when Koopa dodges the returned bombs. Also, the color of the bombs keep changing from black to red.

Continuity: At the beginning of the scene where Dr. Nerdnik builds the Plumbinator, The Mario Bros. change and switch positions, even though they were standing the whole time.

Continuity: When Mario, Luigi, Bunsun and Dr. Nerdnik are about to be crushed by the electric pole, when Luigi moans "we're doomed," he is in front of Mario. In the next shot, Mario is looking ahead while saying "doomed, schmoomed." In this same shot, Mario pulls Luigi over to a nearby fire hydrant, and Luigi moves onscreen from Mario's right. Therefore, Luigi has changed position.

Other: When Bunsun walks up to Dr. Nerdnik to free him, an animation mistake is noticable. Bunsun is far away and she walks up to him, and during this whole sequence her body is in front of Dr. Nerdnik, according to the camera's view.

Continuity: When Koopa brags about his vision, toes, etc, when his goggles come out, the two eyepieces are on his right eye for several frames, then it suddenly changes to both eyepieces on both eyes.

Continuity: In the scene where Bunsun messes up Robo Koopa's controls, everyone's surroundings keep changing in almost every shot, which is basically the floor they are standing on, and the backgrounds.

Revealing: In the first chase scene, the backgrounds are usually repeated in close-up shots, because you can see a sudden jump in the background animation.

Continuity: During the fight sequence, Koopa ties a rope around the Plumbinator's metal body and pulls the Plumbinator over to him. Luigi cuts the rope with a pair of scissors, causing Koopa to fall back. The part of the rope tied on the Plumbinator disappears for the rest of the scene.

Continuity: During the fight, the egg stains on Koopa either disappear or move around him. The stains eventually disappear entirely.

Continuity: The Plumbinator is light blue. It changes to a darker blue when Mario says "May the best machine win" to Koopa.

Other: When Koopa's controls are messed up by Bunsun, an explosive shoots out one of Koopa's toes, destroying a nearby structure. In the next shot, bullet bills are being fired out of his toes.
