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.
My Real Daddy: Porky's creator Friz Freleng actually used the character rather sparsely throughout the series, with other directors, perhaps most notably Bob Clampett, more responsible for developing what would be his finalized personality.
The Scrappy: Apparently, according to several WB sources, Porky Pig is a Scrappy to many creators and executives of the series, explaining his lack of spotlight. Director Frank Tashlin in particular thought Porky was "a terrible character", and resented most of his filmography being devoted to him compared to more abrasive and flexible characters like Bugs and Daffy. It also didn't help that by the 1940's, Porky had become more of Grumpy Bear than the cute protagonist he started out to be. Less prominent with actual fans and animation buffs, who often rate Porky's cartoons highly and consider him underrated.
Vanilla Protagonist: As the series gained it's trademark wackiness, down to earth Porky had increasing difficulty grabbing the audience compared to abrasive newcomers such as Bugs and Daffy. As such his own series gradually fizzled and he was reduced to a co star to the rest of the ensemble.
