The 罐中臭屁 is an 配饰 that the player can equip, allowing them to double jump. Unlike the 云朵瓶, the second jump will allow some propulsion if the jump button is kept pressed, behaving more like the 火箭靴. Also, while wearing 赫尔墨斯靴 or any of its derivatives, the second jump will activate sprinting.
- The 整蛊坐垫 sound effect can be heard while jumping with this accessory equipped.
- The Fart in a Jar is the only propulsion item out of the 沙尘暴, 暴雪, 云, 海啸 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 气球束.
- The Fart in a Jar and Fart in a Balloon don't make the fart sound effect.
