What could happen if you fell through a skylight?

You could get injured pretty bad or die cause I saw a movie called batman returns a lot of bats fly around the penguin and then he lost balence until he fell through a skylight in the sewer and he emerges from the water but drops dead on the floor from the injuries and poisoning but the penguin really died from the toxic waste in the sewer and falling through the skylight so if you fell through a skylight I think you could get injured or die From falling in a skylight
