That sucks. My dad had a deer mount fall on a 30 gallon fish tank. Broke the deer's nose and the fish tank

I fixed a deer head that had fallen off the wall and broke a hole antler off right at the skull plate.
The one I had come down was my own fault. Didn't get the nail in a stud. The horn put a hole in my laminate floor and the deer's nose put a softball size hole in the drywall. We had been in our new house about 3 months

The deer was undamaged luckily. I have knocked a couple off the wall moving stuff around. The last one caught me right in the cheek. The horn went all the way through. Even made the tooth it hit hurt
Yea be careful with those mounts. I have heard of guys screwing them to the wall.
