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

 * This item could possibly be a reference to Saints Row: The Third, which has a weapon by the same name.
 * A fart sound effect is heard when double jumping with this accessory equipped.
