A poo screamer is a special type of creeper made up by Max to scare kids. According to Max, Creepers are green because they're made out of leaves. But a poo screamer is brown... because it's made out of poo. It doesn't hiss like a normal creeper, it makes a large gurgling sound. Beware, this is the most dangerous monster in Ardenvell.
