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.
 * The Fart in a Jar is the only propulsion item out of the Sandstorm in a Bottle, Blizzard in a Bottle, Cloud in a Bottle and itself that has 'in a Jar' at the end instead of 'in a 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.
 * The Fart in a Jar and Fart in a Balloon don't make the fart sound effect.
