We typically pull additional bats flying in the red zone from the blue marker, but the bats are missing (in case they do not count as "patrols").

Additional information:
In your stream you said that the bats are implemented and mentioned the two bats on the right of the red area, but we typically pull 5 extra bats (because we skip the entire trash up to the platform of the first boss), so there are more than these two you mentioned.
