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.
Family-Unfriendly Aesop: Gosh Zilla amounts to Wally overdosing after misunderstanding Mr. Twiddle's medicine dosage instructions, knocking himself out and having a lucid dream about growing to an enormous height and walking through the city as the community reacts to him. At the end of the dream, he's offered a contract to be a movie star before he's suddenly woken up. After Mr. Twiddle explains what happened, Wally then proceeds to deliberately overdose in order to continue the dream as a panicked Mr. Twiddle shouts at him to stop. Great lesson for the kids.
Genius Bonus: It helps to know your The American Civil War terminology whenever Beauregard gets involved. One of his episode's titles even has it (Rebel Rabble, "Rebel" being a term for Southerners who supported the United States).
