Leaf's pack ran down the mountain cliffs towards the ridges. They could see a large moving object
careening towards the main ice ridge. It was green with a strange symbol on it. It had a yellow area on  a circle, and then some black areas.  It was heading towards their mountain. The Inuric  Vine pack was on top of the thing.
                                   HUMAN POINT OF VIEW

On the news, a reporter could be heard.

Reporter: Live on the scene of a runaway nuclear/radioactive train heading right for the smoke ridges mountain in Canada.
If this mountain becomes a radioactive zone, it will kill all of the tourists on the bridge.
Another reason why this could be a disaster is that the beloved wolf packs of the area, the forest pack and the ridge mountain pack, are on the train.
NEWS REPORT OVER
  -Wave's area
Wave looked up and saw the moving object hurtling towards the   mountain. He thought nothing of it.
Oak turned to wave and asked, "What is that thing?" Wave shook his head in response. He walked down the mud path towards the main cave. As soon as he got to the bottom of the pit where the Main den was , he saw some bones. As he approached the bones, he noticed that they were caribou bones.
He padded to the main den along with Oak. Oak spoke to him. "Is that thing about to hit the mountain?" "Yes." Wave ran up the muddy staircase, with  Oak on his tail. A large amount of wolves were on it. There was another group of wolves who leaped on the train from the mountain. Wave saw a way onto it, and took his chance. He and Oak stumbled up the ice wall towards the thing.
