Falling out of the bunk bed and damaging the floor.

Just cut the flooring big enough to work on the area with a very very sharp knife and set it a side. either cut out the damage floor and replace or pour floor leveler in the damage ( assuming there isnt cracks and holes for the leveler to leak out of.

Then just take the piece you cut and glue it back in. You will never see the cut if you do it carefully
goodluck
