Continuity mistake: This is a mistake for the introduction from seasons 2-20 (1991-2009). When Homer screams, he turns round. You see this in a wide shot. There are no boxes to the right of the door in the garage. However, two just appear out of thin air when he runs through the garage. (00:01:50)
Continuity mistake: When Mario, Toad and Luigi are driving to the rebel fort, the seatbelts they are wearing disappear for most of the scene. (00:17:30 - 00:18:40)
The Ringer - S1-E1
Continuity mistake: Zelda has an amateur magician grow a large plant for her to use as a sling shot. He is standing beside Link as it grows and then suddenly disappears between shots. There was not enough time for him to have walked or run away. (00:11:40)
Sukeban no me ni namida? Rûru muyou no kakutou shintaisou kecchaku - S1-E13
Continuity mistake: After Kodachi has used her bladed hoop, Ranma gets the clavettes from Akane. In the close-up she uses them like nunchakus; too bad though that the chain she has at her wrist is gone. (00:06:20)
