Kiss 'N Tell - S1-E4
Continuity mistake: When Spryte discovers the Wall Without End curves down and goes into the ground, the shot of her flying to the last visible spot shows that the last of the wall above ground is going down at a curved angle. When the camera shows a close up of where the wall and ground meet, that part is suddenly going straight down. Also the shape and pattern of the stones at the base corner of the wall changes between shots. The size of the bricks in the very last shot of the wall also changes. (00:09:30 - 00:10:50)
