Factual error: When King Koopa looks in the mirror, the reflection is not reversed. Additionally, it would not be possible for him to get a reflection of Mario and his friends since they are underneath him. (00:12:24)

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.
Mario Mario: We need your Hocus Pocus. Can you make us fly?
Genie: Fly? Do you know what a drain that is on me?
Luigi: No problem. Any drain you got, we can fix. We're plumbers.
Mario Mario: Tell you what, you make us fly and I'll grease your palm with a gold coin.
Genie: Now you're talking. Eeenie meenie miney mo. Make'em fly. I need the dough.
Trivia: When the Quirks uses their noses to play a song to get rid of Koopa for good, they play the theme song from the video game The Legend of Zelda.
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).
