Official Description

This description was taken from official source. Do not modify it.

Do you get carsick? Jack gets bus sick. He shouldn’t have drunk like a hundred lime slushies before boarding Sweet Sally, and because of that, our friends now have to battle a giant puke ghost. Eww! Press play to watch – if your stomach can handle it.


J.B. is racing the Paranormal Intercept Bus 3000 down Newbury as Jack is about to puke from drinking one hundred slushies. After locating a portable toilet, Jack tells J.B. to stop, and he cuts Nanna to use the toilet.

After Jack is finished using the Portable Toilet, he exits, but the stall beings to shake and grumble. He investigates the scene when Spewer comes out of the toilet. Spewer then attacks Jack and uses his Gloom to create a Gloombie out of a Portable Toilet.

Jack defends himself by shooting at the new creation, but it had no effect, as the Portable Toilet spits Gloom from its mouth. Jack retreats to the Paranormal Intercept Bus 3000 and tells J.B. to start the bus; however, the bus gets pushed on its side, due to the Portable Toilet toppling it over.

Facing a tough situation, J.B. decides to risk herself to defend the team, so she uses a secret Crossbow to counterattack. When she gets out, she fires at Bill and Nanna, breaking free from their possession. Spewer spots her and attempts to barrage her, but J.B. destroys him, and thus destroying the Gloombie.

Parker and Jack come out to congratulate J.B., but she immediately approaches Sweet Sally and promises to fix her up.
