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.

Leaf lay on the floor of the medicine den. Wolfclaw was gathering herbs from a rocky shelf.   Leaf was moaning as a pup slid out, and then three more, and one more. Wolfclaw licked all the pups,  and they staggered around blindly towards Leaf. They snuggled into her fur and started nursing.  As Wolfclaw ran around  barking, "The first pups of spring!", a wolf came into the medicine den. The wolf, whose name was Dancing Flower, told Leaf, " Battle by the ridges."
Wolfclaw's eyes widened in excitement. "My first actual battle healing!" he said.
Leaf was in good condition but she could not battle the pack of the Inuric Vine because of her pups.

  Wave trudged through the snow. He heard a sharp rustling sound and turned around. He looked around, and no one was there. He felt like
someone was watching him. Then, a bush moved about and out came Oak.
He bounded towards Wave. Oak came up to wave and asked," I want to join your pack!" Wave said to Oak that it was ok,, but they had to wait until they got to the pack. Wave looked around for a shelter or something close. There was a waterfall, and a group of trees , and a huge wall of ice. There was also a large pit with a group of caves in it. The caves were acessable due to a staircase of dirt.He  barked to Oak, " that is our shelter. Go into it befo-" A strange moving object pelted towards the ice wall, and got on top of it.

Wave woke up to a blast. The humans had been blowing  a hole in a cave for a long time. Wave was tired of the blasting and he wanted to get home . He noticed that a craft of red stuff was near the enclosure. He had an idea...... He took the red stuff and rubbed it on some coal, until there was a spark on the edge of  the red stuff. Hmm, he thought. Maybe this will get me out ! 
A human looked over and said to  Wave [wolves cannot understand humans] "wfatdertharlkraetyodong,wollouf ?"
Wave ran into the cave as fast as he could. A large explosion could be heard. The rest of the wolves woke up. They stuck their heads out of the  cave. A group of other endangered species had already escaped from their   enclosure.  The wolves stampeded out of the enclosure, singing joyful  howls and avoiding bears and wolverines. They leaped out of the area and trudged into the snow.
I am finally free ! thought Wave.
