Nobita no Jack to Mamenoki

Synopsis

Attending a Christmas party in fine clothes, Nobita receives a champagne-shaped gift from visiting Dorami from the future. Grabbing something bottle-shaped, he shrinks and gets sucked into the cork—shocking! Doraemon explains it's the 'Champagne Rocket,' which shoots cork-turned people to desired locations; hitting hard surfaces shatters the cork, restoring size. Nobita gets shot to Suneo's house for the party. But overshooting, he crashes into a giant Christmas cake! Arriving late, panicked Doraemon and Dorami notice Nobita buried in cake. Using 'Small Light' to shrink and help without damaging the cake...!?
