Itchy says that only Annabelle has the power to create magic collars. But that is not true. Red the devil cat has the exact same power.
Although they're cousins, Annabelle and Belladonna look more like twin sisters.
Anabelle: (to Charlie) Long before I met you and Itchy, Belladonna has been looking for ways to mess up my neat and orderly angel existence!
Belladonna: A girl's gotta have a hobby.
Belladonna: (about Itchy) Now, what should we do with this insect?
Carface: Squash it!
Killer: Bonk it!
Carface: Broil him in oil!
Killer: Dress him up in a lumberjack outfit, and make him chop down trees!
Itchy: I'm not going to let you throw your afterlife away like this, Charlie! I'll save you!
Killer: Sure, but who's gonna save you?
Belladonna: I'm not really bad, just... morally challenged.
Charlie: (enters the meat factory) I've died and gone to heaven... again!
This is the second time Charlie has fallen under the power of a magic collar. The first was in the second movie.
When you think about it, if you remove the D and the O, Belladonna spells Annabelle once rearranged.
Sasha doesn't appear in this episode.
Anabelle and Belladonna Sings: Take the Easy Way Out
This episode marks the first appearance of Belladonna.
Carface: Now hear this: Where's the beef?
This is a reference to an old television advertising campaign from the Wendy's chain of fast-food restaurants. The advert in question involved an old lady opening a large burger bun and finding a minuscule patty inside, prompting her to ask: "Where's the beef?"
The cow falling on Belladonna is a reference to the TV series Earthworm Jim, wherein a cow falls on someone at the end of every episode.
Belladonna: You may think you've won, but in the end I'll get you, and your little dog friend, too!
This a play on the Wicked Witch of the West's dialogue in the film The Wizard of Oz.
The episode title is a reference to the 1960 italian film La Dolce Vita.
Bebe Neuwirth's voice of Belladonna sounds alot more like Mirage from Disney's Aladdin.
