As you walk down a path, taking in the bright blue sky and the beautiful land scaping, you wander down a path that's obviously a bit less traveled than most. On a lark, you make a b-line for a pair of willow trees that have grown together, forming a natural hide-a-way in the park.
You sit against one of the tree trunks, where a strange vine coils up one side of the tree. you feel yourself beginning to space out. THe tentrils seem to be coiling around your face. You feel happy, you feel at peace...
...you feel one vine tendril force its way down your throat and into your lungs. Panicked you stand and feel a wrenching pain as the plant digs into the skin of your nose and trechea. It grows, blocking off your air supply. You scream, using up the last of your precious air.
You feel something burst inside your lungs and the urge to cough wracks your body. As you choke, the vine suddenly recoils, leaves falling off as it slowly untwists from your body. You inhale and the air never tasted so sweet. You stumble out into the rest of the park, choking on whatever the vine put in your body. Clouds of yellow pollin float into the air with every cough.
Finally you fall to your knees. A wave of dizzyness wracks your body. You rest your head on the ground while the last of the coughing fits wears itself out.
Then you sit up and stare at your hands.
