Also, the color of the bombs keep changing from black to red. (00:10:20)

Continuity mistake: 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. (00:07:10)
Robo Koopa - S1-E52
Continuity mistake: 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. (00:02:10 - 00:03:30)
