The Mystery Machine drove out of Crystal Cove as Scrappy scaled the size of Scooby's butt with the size of the van. "You're lucky uncle Scooby. If your butt was any bigger it'd be causing some damage to the Mystery Machine just by coming in."

Scooby looked at his massive butt, glad it was able to fit into the Mystery Machine, even if just barely. "Yeah. I guess you're right." Scooby suddenly cut a five second fart, reeking of rotten eggs and letting out a yellow cloud with his butt vibrating (phhhhhhhhhht).

Scooby sighed as Scrappy laughed, arching his butt up and releasing a three second fart that reeked of moldy cheese (pffffft). When he turned around, he started explaining the situation as Fred rolled the windows down. "Well then, I might as well start explaining the situation to you guys. Someone called The author has a love for writing characters farting." Scooby suddenly released a loud and bassy ten second fart, one that reeked of liver and made his butt vibrate while unleashing a green cloud (PFFFFFFFFFFFFFFFFFFFFT). "Me and uncle Scooby fell into that trap."

"The Author, huh?" Fred felt like he'd heard that before, hoping there was a chance they could find him. "Two questions Scrappy. Where is he, and why did he make Scooby's butt bigger?"

"I think he lives in a dark forest called the Swamp of Gasbuttica. Dumb name, I know. As for uncle Scooby's butt, I'm not sure." Scrappy explained, and then he and Scooby both released two loud and bassy ten second farts, unleashing two yellow clouds of rotten eggs that made their butts vibrate (PFFFFFFFFFFFFFFFFFFFFT). Scrappy laughed a bit as Scooby covered his face in humiliation. "This is gonna be a fun ride."

The rest of the Mystery Gang groaned in annoyance, knowing the trip to the Swamp of Gasbuttica was gonna be a long one with Shaggy speaking up. "Any chance we can find a shortcut to this place?"

"Yeah, I know a couple. I may point one out since, as fun as it is to fart on you guys, I don't want this thing around forever." Scrappy answered, indicating that he would wait for the right moment to point out when a shortcut was nearby.
