When the snow falls it means the fun can begin for one boy and his best friend...a giant polar bear called Mister P. There are snow dens to be dug, snow bears to be created, and a toboggan race! All the children of Overwell are busy building the best toboggan EVER in order to beat their rivals in the race. But disaster strikes during the practice run...Mister P is too heavy for the toboggan and now it's in pieces. The children are NOT HAPPY. As Mister P slides sadly down the snowy hill, his head hung in shame, the boy has ingenious idea. Surely Mister P would make a better toboggan than anything built from wood and plastic, wouldn't he...?
