Me and my friend were messing with the training dummy's in the main lobby, and when using the fishing rod and pulling it in various directions, we found that the dummy model would disconnect from the shadow/hitbox when pulled with the fishing rod. Also, when the dummy over the pit was dragged underneath the oak tree to the right of the practice area, it disappeared altogether for my friend, despite me being able to see it, but not able to attack or pull it with the fishing rod.
