Woody's friends warn him that the groundhog has predicted a blizzard. Unconcerned, Woody decides not to go South with his pals. Soon enough, the blizzard sweeps in and destroys the loony woodpecker's stash of food. Facing starvation, a glimmer of hope arrives in the form of a cat. The cat is also starving and it turns into a match of brawn and wits to see who eats who.
Woody Woodpecker spends his day singing loudly and pecking holes in trees. He infuriates the other woodland creatures - when he isn't baffling them with his bizarre behavior. Woody overhears a squirrel and a group of birds gossiping about him. Even though he just sang a song proclaiming his craziness, he denies their whispered accusations that he's nuts. But after they trick him into knocking his head on a statue, the poor bird hears voices in his head and decides the animals might be right. He decides to see a doctor.
Mickey is performing routine maintenance on his tugboat (with interference from a pelican) when a call comes on the radio that there's a sinking ship needing assistance. Sadly, Mickey's crew consists of Donald and Goofy, so getting underway to help is not easy. Goofy has to fight a boiler's door to get it stoked with coal (and when he succeeds, he overfills it) and Donald gets tangled up in the machinery. Not to mention that nobody casts off, so they drag half the dock along with them. The overworked boiler soon explodes.
In this Ripley's Believe It or Not! parody, some of the supposed curiosities we are shown are a man who daily drinks fifty quarts of milk, the world's loudest hog caller, a human basketball, a new giant telescope showing life on Mars, and a man who saws people in half.
The Lone Stranger is sleeping when his faithful, if overly caricatured, Indian scout sees stagecoach driver Porky being robbed by a bad guy.

But just in the nick of time, the Lone Stranger recovers and conquers the bad guy. Meanwhile, Silver and the villain's horse have been having their own close encounter, and Silver returns with several little colts.
As a narrator describes the scene, we watch the whole Katzenjammer clan camping in the park of the title, a composite of several national parks in the western USA.

Mama has a run-in with the law for picking a flower; The Captain has his own for feeding a bear, which turns out to be a ranger/cop in disguise.

The Lord sees that the stock value of "Pair-o-dice" is dropping on the exchange so he dispatches a slow-witted and slow-talking angel to sinful Harlem to recruit new customers. When this fails, God finds success sending a group of musical angels with a little more swing in their style, so much so that even the Devil wants to join up! One of the “Censored 11” banned from TV syndication by United Artists in 1968 for racist stereotyping.
