Help me overthink why a nun wielding a violin bow is in a lake.

• Violence was anticipated enough for the guys in the background to bring weapons, but it seems like there was some sort of ceremony with music to have the violin present in the first place.

• In this universe, are flamingos normally violent? Or did they turn violent during the nun’s recital? Did the music cause the flamingos to go crazy?

• maybe these people were involved in some sort of time travel hi-jinx, considering the vaguely prehistoric setting
