Is there an expert on Prius anatomy?Discovered a hole in the roof of my 2009 Prius and now it is infested with mold. I need to know which way the water goes and where it is collecting without cutting my car in half.

The hole is about as big around as a finger or a medium sized bullet, but is only on the exterior of the car— there is no damage to the interior. The hole is toward the front slope of the roof, so water is only going toward the front of the car. I am going to a mold specialist ASAP but in the meantime I really would like to know a couple things: 1. Could this be from a gunshot? Would a bullet not penetrate through to the interior of my car? 2. Is the water draining very slowly or is it in there sealed tight with no way to get it out?

This car is paid off and perfectly fine otherwise, so I’ll do anything to save her. Looking for someone who has an in-depth knowledge of the inner workings of a Prius, so I can guide the people who will be removing the mold. I need to know if it is even worth trying to remove. Do you think it can all get removed? I’m at a loss and going to also post in a mold-related subreddit. Thank you in advance. This picture was taken before I was even aware of the hole— I have since stopped driving the car
