I have done all that can be done to keep those little bast@ards out. I am sick to death finding bats up here every time I venture to the Bat Cave.
If I am forced to I will use grenades.
The books on the left were all written by me and sometimes I dive in to a different era. Not lately though, on account of the damned bats living on top of them.
I had a little help with the sign for the window.
