These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
After Mulberry prevents some cartoon all-stars from making Jack endure anti-piracy lectures in "Jack the Ripper," she never mentions meeting them again. Word of God says this was originally going to be part of a Brick Joke, with additional cartoon characters appearing later to lecture Jack, but the second scene would have disrupted the flow.
Mulberry does some pretty random things after Brittany Murphy's death in "Murphy's Lawn" causes her to think about all the people she took for granted lately.
Bizarro Episode: "Mulberry's Epic Yarn" starts out as a parody of Kirby's Epic Yarn, then becomes progressively stranger, until they reveal that Mulberry wrote the issue herself, apparently warping hers and Taffy's reality.
When Mulberry's wards in "Heiress A Parent" start laughing wildly at news reports about the "weinergate" scandal, Taffy tells them about a PSA in which a man laughed so hard at dirty jokes, he turned into a donkey, then exploded. Taffy then asks the children if they want to die that way.
