Fart in a Jar

The Fart in a Jar is an accessory that the player can equip, allowing them to double jump. Unlike the Cloud in a Bottle, the second jump will allow some propulsion if the jump button is kept pressed, behaving more like the Rocket Boots. Also, while wearing Hermes Boots or Spectre Boots, after the second jump the sprinting is activated.

Trivia

 * The Whoopie Cushion sound effect is heard when double jumping with this accessory equipped.
 * Unlike the other propulsion items, the Cloud in a Bottle, the Blizzard in a Bottle, and the Sandstorm in a Bottle, the Fart in a Jar is the only one with "Jar" instead of "Bottle".
 * The Fart in a Jar has the same jump height as the Sandstorm in a Bottle, but cannot be used to make a Bundle of Balloons.
 * In mobile the Fart in a Balloon and the Fart in a Jar doesn't make the fart sound effect
