The Simpsons’ Treehouse of Horror #21

Ned Flanders believes he has missed ‘The Rapture’ until he discovers that everyone who has been left behind is left-handed! Then, Apu accidentally receives a shipment of adorable gremlins intended for the sorcery shop a few doors down the block; unfortunately, he doesn’t read the warning that tells him not to feed them Squishees after midnight. And visit the ‘metropolitan’ world of Fritz Lang (Simpsons-style), when the idle rich championed by Mr. Burns clash with the working poor led by Marge Simpson.

"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
