Follow Your Nose

""Wait. A pie with hobo-lifting aroma? Who baked it?""

- Bender, Futurama, "The 30% Iron Chef"

For humans sense of smell is one of the main ways we are drawn to food, so this naturally shows up a lot in fiction.

In comedic or cartoony situations, a character will be shown being physically lifted off the ground and floating toward the source of a delicious smell. In older Looney Tunes-style shorts the vapors of scent will often be clearly visible, physics aside, and sometimes the vapor will actually develop hands that will lift the character.

Particularly Genre Savvy villains will sometimes build a trap around this trope and ensnare an unsuspecting hungry person.

Often an example of Editorial Synaesthesia.

Advertising

 * This is the main shtick of Toucan Sam in the Kellogg's Froot Loops commercials, hence the trope name.
 * A Lowes commercial uses this with the smell of fresh cut grass signaling the start of spring.

Anime and Manga

 * In Miyazaki's Spirited Away, Chihiro's parents find a spirit restaurant by following their noses and proceed to gorge themselves on the food. Only Chihiro resists eating it, and good thing, too.
 * In xxxHolic, Watanuki finds the Fox Spirit's Oden cart this way, and eventually forms a strong friendship with the shop owner's son.
 * After sniffing around for a while, Mikoto in Mai-HiME is drawn to a kendo dojo in the second episode and initiates a Fire-Breathing Diner after stealing some super-spicy curry bread.
 * Variation: In Wolf's Rain the wolves are drawn to Freeze City by the smell not of food but of lunar flowers. The scent ultimately leads them to the Flower Maiden Cheza, whom they hope will show them the way to Paradise.
 * In One Piece, Luffy often forgets what he was doing and runs off if he smells food somewhere.
 * Non-intentionally hillarious: Baki the Grappler shows us how reanimating the frozen body of the Jurassic man, Pickle, seems unattainable... but he awakes on his own after smelling.

Newspaper Comics

 * In a subversion, Garfield actually puts a hand to his ear and rushes up to Jon holding an icecream cone, to which Jon incredulously replies "How can you hear icecream??"
 * This often happens to the dog Louie of Overboard when something is cooked on a barbecue.
 * In Over the Hedge, a woman had gone into labor (at home), but the baby just wouldn't come out. So the friendly neighborhood animals put their heads together: "If you had to pick one thing to convince the baby that life's worth living, what would it be?" They cooked up a batch of chocolate chip cookies, used a fan to blow the scent in through the window, and the baby leaped out of his mother, sniffing eagerly at the aroma.

Literature

 * In Who Cut the Cheese? by Stilton Jarlsberg, one of the rats in CheesyUniverse tells Ho that the rat found CheesyUniverse by following not the smell of cheese but another rat's scent: literal brown nosing.

 * Parodied/inverted in The Young Ones:

 * Many, many Tom and Jerry shorts feature this, usually with Tom's use of cheese to ensnare Jerry.
 * A sleepwalking Spike following a steak-on-a-pulley, squashing Jerry in the process.
 * Early lampshading: in Mickey Mouse's The Little Whirlwind (1941), Mickey is lifted through the air to Minnie's house by the scent vapors of a delicious cake. Before getting the whole way there however, Minnie shuts the window from which the vapors emerge... and the vapors instantly react by dropping Mickey.
 * The page quote comes from the Futurama episode where Bender attempts to become a chef, and this trope is parodied by a couple of hobos who float off the ground thanks to jetpacks upon smelling Yoda Spargel's pie.
 * Wilma's Yabba-dabba-dooberry pie on The Flintstones tended to have this effect on anyone who smelled it.
 * Happened to Monterrey Jack on Chip 'n Dale Rescue Rangers whenever he smelled cheese. At least once, this was used to trap him.

 * In A Pup Named Scooby Doo, Scooby's nose would sometimes cartoonishly pop off, and Scooby and the gang would literally follow his nose.

 * Hey! Who left this pumpkin pie here?
