One week to go 'till Christmas Day, The final touches underway, A ribbon here, a flourish there, And presents piled up everywhere. Santa smiled. 'What could go wrong?' He didn't have to wait too long . . . Out of the sky a whirling blur, Of antlers, legs and soft brown fur, Came crashing through the workshop roof, And that's how Rudolph sprained his hoof . . . Oh no! Another Christmas disaster! The sleigh can't fly without Rudolph. Luckily, head engineer Lizzie is on hand to help . . . introducing ROBO-REINDEER! Christmas is saved once more.
