Mickey Mouse and the Marvelous Smell Machine is an illustrated text story. It features Mickey Mouse, Minnie Mouse, Clarabelle Cow, Daisy Duck, Horace Horsecollar, Huey, Dewey, and Louie Duck, Gyro Gearloose, Little Helper, Morty and Ferdie Fieldmouse, Scrooge McDuck, Donald Duck, Goofy, and Grandma Duck. Pluto appears on the cover of the re-released edition of the story, but not in the story itself.
It's "Gay Nineties Day" in Calisota, and Mickey and his friends are getting dressed up for the big parade. There's only one problem: all of the old clothes have been in the attic for so long that they smell of mothballs. Mickey visits Gyro, who gives him a phonograph-like machine which can emit any smell. Mickey uses the machine to emit a lavender smell onto the clothes, and then, because he can't turn it off, leaves it on the step.
Unfortunately, while everyone is preparing for the parade, Goofy comes by and picks up the machine, thinking that it is Mickey's donation to the antiques fair, and accidentally turns it on, causing it to emit a pepper smell which ruins the festivities in the middle of town. Mickey learns that Goofy sold the machine to Scrooge, who wants to fix it for Grandma Duck's birthday. Mickey races to the Money Bin, where he finds that Scrooge has activated the machine, causing it to emit a smoke smell. The smell and sight of the scent cloud billowing from the Bin tricks the fire chief into thinking that there is a fire there, and has his firefighters spray the building.
Scrooge's money is now wet and smelling of smoke, and he angrily gives the smell machine to Donald, telling him to get rid of it. Mickey then rushes to Donald's house, which is covered in bees thanks to Donald causing the machine to emit a flower scent. Mickey borrows beekeepers' gear from Grandma Duck, rushes into Donald's house (accidentally letting the bees in), grabs the smell machine, and runs away, leaving Donald to hide in the broom closet while the bees swarm his house. Mickey brings the machine back to Gyro, and, with the town free of unwanted clouds of scent, the parade finally begins.
Behind the scenes
Mickey Mouse and the Marvelous Smell Machine was published as a stand-alone book by Western in 1979. It was later re-released with an alternate cover and title, Mickey Mouse Scratch and Sniff Book, in 1990. Both versions of the book feature labels which, when scratched, smell like one of the scents featured in the book.
