Two Plumbers and a Baby - S1-E17
Continuity mistake: In one scene, Luigi is wearing the same colour hat as Mario, and when Mario opens his mouth to talk, it's Luigi's voice we hear.
Question: Why was Toad's color palette sometimes way different, primarily in the first couple of episodes? Why didn't they bother changing this with the final results? It's relatively inconsistent on what palette is used in each episode, despite the fact the more recognizable of the two (white mushroom with red spots along with a variety of coloring in clothes) is shown much more often than the other (red mushroom with white spots along with the majority of his clothes being red and white).
