* AdaptationDisplacement: Given that there were only four books published in the original series and the only ones published afterwards were [[RecursiveAdaptation based on the show]], it's probably not well-known by now that the show was actually based on a picture book property.
* SugarWiki/HeartwarmingMoments: Come on, the bond between the four main protagonists is enough to warm your heart. Especially between Stanley & Dennis. Sometimes Dennis acts like a sort of father to Stanley, which makes it even sweeter. There's some pretty tender moments between Stanley and his family members too at times. The song "Just You and Me" is a good example.
-->'''Mr. Griff''': ''It's just me and you / And to tell you the truth / It's awfully nice just having you around.''
-->'''Stanley''': ''It's awfully nice just having you around.''
-->'''Mr. Griff''': ''Aw.''
* NarmCharm: The song "Good as Gold". It's so incredibly corny, but you will [[TearJerker want to cry]] when it's done (for context, Dennis sings it when he's convinced that Stanley went to the pet store to replace him with a better fish). What makes it even sadder is that this would have been the SeriesFinale if it hadn't been renewed for a second season! It doesn't hurt either that Dennis' appearance and musical styling in the song is intended to evoke the image of Music/EltonJohn, something which was confirmed by one of the show's storyboard artists.
