Like Herman and Katnip's Christmas Entry, Mice Meeting You, Baby Huey's is by and large simply a retooling of his own one-trick-pony plots with Christmas adornments. The Fox is after Huey and it's Christmas.
As usual with Harveytoons, tho they look like knockoffs of Merrie Melodies, which essentially they are, plotwise, they give a hard hint of the complacency to what life may have been offering, even tho this was the fifties.
As the fox is walking thru the snow trying to find food, looking in garbage cans, he pulls his belt tight. Well, he hasn't been eating, but then he cuts off the excess belt to give himself something to chew.
Not saying people did this, it still shows a peculiar awareness that the fifties wasn't Beaver Cleaver and Donna Reed, and people were going hungry.
From there, the cartoon goes into fox pursuing duck with Christmas garnish.
Even the final joke was a rehashing; Mother Duck has received a fox fur before as the skeletal fox runs away in the distance.
