A freezing wind howled across the ice. Snow flew into the eyes of a small sabre-toothed squirrel – the only creature to brave these barren wastelands.

The scrat – as we will know him from here onwards – clutched a small object to his chest. He needed to bury his beloved acorn, so he would have food after the winter. He attempted to drive his acorn into the ice, to no avail. Scrat whimpered. He had to bury his acorn.

He tried again and again, scratching the ice here and there. His large eyes scanned the white plain, for any sign of soft snow to bury his prize.

Finally, Scrat found what he was looking for; a softer patch of semi-compacted snow. With a squeak of triumph, he raised his acorn above his head and drove it into the ground.

It stuck halfway in. Scrat growled. He continued to push and twist the acorn, trying to get it completely covered. When that didn't work, he started jumping up and down, hammering the acorn into the ground.

Suddenly, a crack emerged from under the acorn. Scrat watched in horror as it spread across the ground, and up the face of a tall glacier. The crack reached the top. Then, the entire glacier started rolling towards Scrat.

The sabre-tooth squirrel promptly ran in the opposite direction. Then he remembered he had left his acorn in the path of the avalanche.

Scrat ran back and attempted to pull the acorn out of the earth. No use – it was stuck fast. The squirrel wailed in despair.

Finally, the nut popped out of the ice. But Scrat was not out of trouble yet. Giant chunks of knife-shaped ice were flying at him.

The sabre-toothed squirrel ran for his life, still hugging his acorn. Tall fir trees disappeared under the rapidly-moving glacier.

Scrat continued to sprint away from the avalanche. Suddenly he screamed, and screeched to a stop. There was another glacier coming towards him from the opposite direction. He was trapped!

But… no! Scrat could still see another way out. He ran towards a cliff. The sabre-tooth squirrel would rather fall to his doom than be crushed between two walls of ice.

Above him, the glaciers met. Scrat skidded towards the opening, tantalisingly close, yet so far away. He wasn't sure he was going to make it yet. The glaciers were brushing his fur. He pushed towards the narrowing crack.

POP! Scrat flew out of the crack and launched into the bright blue sky.

As he soared through the crisp, cold air, he noticed his acorn flying next to him. With a squeak of delight, Scrat grabbed it and clutched it close to his chest. Then he realised that he was falling. And the ground was a very, very long way down. The sabre-tooth squirrel screamed as he plunged downwards.

THUMP! Scrat smashed into the ground. Slowly, he lifted his head. His acorn was missing! The scrat sniffed about for any trace of his beloved nut. Just when he was about to give up, a large, hard object hit Scrat's head. His acorn!

Just as Scrat was about to pick it up, a giant, heavy hoof squashed him into the ground. When the hoof lifted, Scrat groggily looked around. Animals were everywhere. Dodos, starts, birds, turtles, and aardvarks were all heading south. Scrat had fallen into a great migration.

Before he could pick himself up, however, the squirrel was run over by a rotating wheel, and he stuck to it like glue.

Scrat groaned as he was pulled away from his acorn.

Yay! First chapter up! I would really like to hear your opinion so please review!
