<P> On a summer day a young boy named Billy and his mother arrive at the house, which they have just moved into . Billy helps his elderly dog from the removal van and they enter the property . As autumn arrives it becomes apparent that Billy's dog has died and one can see the family burying him in the back garden . With Christmas approaching Billy writes to Father Christmas in the form of a hand - drawn picture; the one and only thing he asks for is another dog . In his excitement, at the prospect of posting the letter, he stumbles over a loose floorboard in his bedroom and beneath it discovers some toys including a toy aeroplane and a small box tied with tinsel . Within the box he finds a photo of James and the Snowman along with the original scarf, hat, coal lumps and an old dried up tangerine (once the Snowman's nose). </P> <P> As Billy realises his discovery he peers out of the window and it has begun to snow . He rushes out to build the Snowman, portrayed in the photo, but after barely completing his lower body he realises not enough snow has fallen to complete the task, having already used the entire covering of snow in the garden . He hurriedly runs around the yard salvaging every bit of snow he can find off fences and a shed's roof and suchlike . Adding the final touches to his creation he decides that the original dried tangerine is long past its usefulness so, discarding it in the garden, he claims a fresh one from a fruit bowl in the kitchen . He finally completes the Snowman and in memory of his own dog uses the remaining snow to build a little snowdog, next to the Snowman, with mismatching socks on sticks for ears, gloves for spots and the discarded tangerine for a nose . </P> <P> Night time approaches and Billy goes to bed and drifts into sleep . As midnight arrives, he is awoken by the barking of a dog in the garden . Billy looks out of his bedroom window, and is astonished to notice the Snowdog waggle an ear at him . As Billy rushes downstairs he finds, to his surprise, that his cold companions have miraculously come to life . The Snowdog, sniffing around in the snow, uncovers the ball that had once belonged to Billy's dog and starts to play with it . The ball bounces into the house and both the Snowman and the Snowdog enter the abode . The Snowman sees the photo of James and his former self on the fridge and smiles . Before too long Billy realises that the Snowdog has started to melt after sitting too close to the fireplace in the kitchen . The party thus ventures outside and explores the garden shed where the motorbike, which the Snowman rode in the first film, can still be seen along with some other mementos from James' family home . </P> <P> It isn't long before the three of them are off into the air to visit the annual snowman party in the frozen north . However, whilst flying, the Snowman loses his nose and as they land to search for it they come across an old - style red single - engined light plane with open cockpit that they use for the rest of their journey . During the flying sequence, as in the original, a number of famous English landmarks can be seen, such as The Shard, London Eye, Big Ben, The Gherkin and the Crystal Palace transmitting station, as the three of them fly over London . </P>
