Kia Smells-new girl help please

Hi all, I am trying to figure out what this smell is in my Kia..It is just plain nasty. About a month ago, I took a vacation to the beach and thought I hit a bird. (It flew under never came up), I smelt a dead rotting smell in my truck. :disappoin Blew water through out the entire thing hoping to get rid of it. That didn't work! :banghead:

What can i do? I smell something and am not sure where it's coming from. It used to be in my left ac vent, but now you can smell everywhere. I am a scenty person and let me tell you this sucks!

Any advice would be helpful. I saw the one post about the drain, but I have no clue where that is located.

Thanks so much, frustrated me!
