The poison forest is really rather remakable. Depending on which section your in, the trees could be blue, or purple. Of course, if the angel is upset, the trees could unroot themselves and chase you around while shooting you with poisonous darts. See? Remarkable.
But really, walking there on a good day could a wonderful experience. The landscape is beautiful, with small streams and natural waterfalls. Things are never the color they are supposed to be, simply because everything in the poison realm is made of the angels own poison. It is made to be non toxic, and totally harmless...... but like i said the trees unroot themselves when she's mad so you might want to tread safe waters here and be nice to her greenery......or... bluery. (I dont think that was a word before but it is now!!! :) )
