This episode contains examples of the following tropes:
Cymbal-Banging Monkey: One of Quackerjack's toy soldiers is a life-size wind-up cymbal-banging gorilla.
Early-Installment Weirdness: Mr. Banana Brain's design looks like a full-on parody of Mr. Potato Head but with a banana instead and was merely an explosive used by Quackerjack to cover his escape. All his other appearances made him look less like Mr. Potato Head and had him become a ventriloquist dummy used by Quackerjack.
Just Desserts: Quackerjack is eaten by Gator Gal in the end. He is still alive as he cries out inside her belly, "I don't like this game."
New Media Are Evil: Quackerjack hates video games, and considers them inferior to traditional toys, to the point where expressing fondness for them in his presence really ticks him off. He blames video games for the bankruptcy of his toy company and for him becoming evil.
Out of Order: Despite this episode clearly being Darkwing's first encounter with Quackerjack, it aired after he already made several appearances.
Parental Hypocrisy: Gosalyn calls out Drake for telling her that video games will rot her brain, only to catch him playing video games and signing up for the same video game contest she signed for.
Swallowed Whole: While trying to get out of the game, Quackerjack ends up getting swallowed by Gator Gal.
