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.
YMMV: Brawl in the Family
Broken Base: The forums have been divided on whether or not the more serious, story-driven Cocoon Academy arc is a good thing, or if the comic should stick to quick, cute gags.
Crowning Moment of Heartwarming: When he's introduced, it's clear Eario desperately wants to be related to his hero, Mario, somehow. There's the obvious moment at the end of the Janitor of the Mushroom Kingdom arc when his son, Waluigi, invites him to his own family reunion, but there's also the fact that they are indeed related, though it takes some Fridge Brilliance to figure it out: according to Nintendo, Waluigi and Wario are brothers, and Mario and Wario are cousins, making Eario Mario's uncle. This can very quickly become a Tear Jerker if one realizes Eario will probably never know that, however.
Rescued from the Scrappy Heap: Waluigi was originally created so that Wario could have a partner in Mario Tennis, and was disliked by critics and players alike. Years later, in comes this comic, turning Waluigi into a psychopathic Cloud Cuckoo Lander, and he quickly became one of the best characters in the strip.
And Eario, the janitor of the Mushroom Kingdom. He cleans and polishes (and refuels the bullet shooters) all for his idol Mario, and the day he got a coin from a block Mario hit was the happiest day of his life. Until he was reunited with his son(?), Waluigi.
Young Dedede in the Cocoon Academy Story Arc. First he gets into a food fight by accident, is sucked up by "Pinky," and gets detention for aforementioned food fight. When he gets home he has a terrible dinner (so says the mouseover text) and the next day he's sent to Headmaster Hand's office. And then later on, he thinks that he's lost "Pinky" as a result of fighting Dark Matter...
Luigi can't fantasizeHIMSELF being the hero. Also, Matthew saying he has low self confidence doesn't help...
