I need some help on Avatar (Gameloft) the game. I'm on Chapter 4, the Tree of Souls, and I'm right by the tree. However, the tree is surrounded by a shitload of purple plant things that hurt (and will kill) me when I try to get to the tree. And, even when I get to the tree I don't know what to do, and I die. For additional detail, there are small dog-like animals chasing me, and there are about four of those flower-plant things that can heal me. Help?
