Stay strong against Grim Flamingo

"This is part of the Grim Flamingo saga. I came across a text in "New Yorker" magazine;
it was about the notorious killer, Perry Smith, the "short-legged".
He recounts in detail a story about a strange yellow bird, which always comes to help him in difficult times and saves him from his feverish raving and woeful lot.
I immediately thought of another bird - its exact opposite - Grim Flamingo.
In his youth, he looks almost like the yellow bird, but after he gains strenght and grows feathers, he develops an intolerable and evil temper.
Grim Flamingo is like a black hole, like a crooked mirror.
His essence is immaterial, so he cannot be defeated."
