The pants look almost the exact same as SpongeBob's regular pants, except they inflate into a bigger size, as the name implies. The top part is white in color, and the bottom is brown with black, straight stripes going across the center. There is also a red tie attached to the top.
Role in series
The pants seem to be activated by a pull-switch that triggers its wearer to have the pants lift them aloft, only to flip upside-down because of the weighted pressure, as demonstrated by Patrick. The first version of the pants had the ability to irreparably burst off the wearer, upon their request.
"The Sponge Who Could Fly"
The pants make a more prominent appearance when SpongeBob places a hair dryer in his pants, causing them to inflate. They are later shot down and burst by Cannonball Jenkins.
Lights, Camera, Pants!
