The Snow's Hot, Hot, Hot!

Doraemon applies a special gadget on himself and Noby called "Turvy Topsy Cream" which does hot and cold things backwards and lasts for 1 day. When snow falls on Noby and Doraemon, it makes them boiling hot, so Sneech and Big G throws ice cold water at them,but it made them extremely boiling hot. This leads to trouble when Doraemon and Noby (clad only in his underwear) get caught outside in a snowstorm, seek shelter in a truck, and end up in the snow-covered mountains. Is there a chance to get back home before another snowstorm?
