Go to Draynor Manor. Go up from lumber bridge, then
go left until you get to a road with four lines. Go up and try
to chop the tree by the dead bush. You will not be chopping it.
Instead, you will see the dead tree hit you and distract you until
you go away. At anytime you find some of these, sometimes they
will attack you. Also, in the wilderness (levels 3 to 9), you
can try to chop a tree, but you will not chop it. It will turn
very weird, and also break your axe. Note: You cannot use this
trick to die.
