Gekiretsu shoujo Shanpû toujou! Watashi inochi azukemasu - S1-E15
Continuity mistake: When the chase at the ending of the episode begins, Shampoo smashes her chui on top of the wall in front of the room with the panoramic view of the pond (the one we see always featured). She does a little bit of damage to it, a bit more of a beach-ball size chunk turned into dust. At the end of the episode Soun Tendo is staring at the garden and that section of the wall has a huge crack, destroyed for at least half its height. (00:18:50)
