Let's worship some animals.

Alright guys, since the Crow and Koi Fish are immortal, I think it's safe to say they are gods. 
The Crow is Lawful Neutral, constantly judging from atop his perch. The Koi Fish is the destroyer of worlds wishing to eat all in it's path. Chaotic Evil for the Koi Fish. 
Anyway I'm just trying to start a religion and convince people to make shrines for the new deities.

I'm in. ALL HAIL THE IMMORTAL CROW AND KOI, THE GODS OF THE BACKYARD. WE SHALL BOW DOWN TO THEIR GRANDEUR, AND PRAY THEY DO NOT DESTROY WITH THEIR MIGHTINESS AND STRENGTH.

The koi fish can eat literally anything in the game, but it only tries  to eat tadpoles and you. I agree about the crow though, especially since it seems immune to the haze gas.
