Linny, Ming-Ming, and Tuck must save one of Santa's reindeer that is stuck on the ice in the North Pole. They make a net out of Ming Ming's sweater and reel the baby reindeer in. Once they save the reindeer she ends up running away because she doesn't have the confidence to think she is good enough to help pull Santa's sleigh.
Linny and Tuck have to save Ming-Ming before it starts to rain after she gets stuck on the top of the schoolhouse building roof and unable to fly due to getting covered in sticky tree sap, just as she ventures out on her own by trying to help alongside with a baby squirrel in the tree outside the school.
