It is the only stamina replenishing item in the level, there is an infinite source for them outside in the woods. I kinda find it funny how you are ignoring most of the image except the mushroom (and yes, there is an achievement dedicated to them, but Alice doesn't eat them).
That was literally what I was thinking xD. I was going to livestream soon today, and I was going to show the level off to everyone. I was going to show off the nuclear pigeon but got the idea that maybe I should not show how to get it as you can abuse the item to your advantage fairly easily.
