While helping Franklin clean up his father's lab, Ronald and his pals stumble across a time machine. Hamburglar dreams up a crazy scheme to use the time machine to get out of cleaning and they end up getting lost in time. Their time travel adventures take them to prehistoric times where the time machine is nearly digested by a Tyrannosaurus and they meet their cavemen ancestors, the medieval times where they impress the crabby King Murray with a musical number to save captured Birdie, the wild wild west where they discover Hamburglar's ancestor Henry H. Burglar II, whom the residents mistake Hamburglar for, and the disco era of the '70s where they briefly encounter Mayor McCheese.

Frosty the Snowman goes where he is needed most, and the town of Evergreen sure needed a visit. Mr Tinkerton, the mayor, runs a tight ship, and there's no room for talk of magic or any other such nonsense. But, when Frosty the Snowman blows through town, he shows the town's children that magic is real. Tinkerton's sons, Charlie and Tommy, along with their friends Sarah and Walter, want to spread the word about Frosty's fun-loving, magical antics but meet resistance from Evergreen Elementary's dastardly principal Hank Pankley. In the end, good wins out, and all the citizens of Evergreen happily learn that magic is real and fun is for everyone!
