The Leap Home (1) - November 25, 1969 - S3-E1
Factual error: The Post Raisin Bran cereal box sitting on the Beckett family breakfast table in 1969 has a 1990s box design. (00:18:00)
Factual error: After Ganon captures King Harkinian, he takes him to a circular room and says that Link and Zelda have one hour to surrender the Kingdom of Hyrule and the Triforce of Wisdom or the King will fall a very long time. After he says this, a bright light shines up from the center of the room and begins expanding, it being a hole. However, it is expanding WAY too fast to take an hour to make the King fall to his doom. At the rate of expansion, it would be to the edge of the room in probably just over a minute if not less. (00:06:55)
Robo Koopa - S1-E52
Factual error: Koopa tries to kill the Mario brothers, Bunsun and Dr. Nerdnik by pushing an electric pole at them. Mario and Luigi use a nearby fire hydrant to protect them by having water rush out of it and keeping the pole from crushing them. There is no way a single blast of water can stop a large pole from falling, and the brothers would have been electrocuted as soon as the water hit the pole. (00:07:00)
