Bellows

A bellows or pair of bellows is a device constructed to furnish a strong blast of air.

Mainstream Smurfs Media
Bellows appear in most episodes of the Smurfs cartoon show, but they were dominantly seen in the comic book story "The Purple Smurfs" and its cartoon adaptation of the same name. The Smurfs used them to contain Tuberose Pollen in order to cure their fellow Smurfs of the Purple Smurf disease.

Hero: The Guardian Smurf stories
Bellows appear in the story, "Attack of the Purple Smurfs", where they were used by the Smurfs and their Smurfette counterparts in order to cure their fellow Smurfs from the Purple Smurf disease. But it got to the point where Saviour and Oracle were the last two surviving Smurfs and they were saved when an explosion occurred in Papa Smurf's laboratory, causing all their gathered Tuberose Pollen to fly high into the air and cure all the infected Smurfs.
