Trailer Breakdown: Tarantula’s SDCC2017 Sneak Peek

Meet “Booty”. Not much is known about this character as I don’t recall him from the web series, even after re-watching all of the episodes. That said, Booty provides for a funny yet different approach to being an overweight dude in cartoons. While most fat guys like Peter, Homer, and others usually are proud of their physique, Booty seems to be a bit more bashful about his appearance.
"There are also other characters that come and go (also owned by the Warner Bros. Discovery conglomerate media company)."
Huh. Is that just referring to other characters from the show itself, or is this implying that the new season is going to have cameos from other WBD IPs
