Big things are happening on TV Tropes! New admins, new designs, fewer ads, mobile versions, beta testing opportunities, thematic discovery engine, fun trope tools and toys, and much more - Learn how to help here and discuss here.
Clumsy Copyright Censorship: The song covers in SMBSS and a few SMB3 episodes being replaced by instrumentals from the latter series, most notably an instrumental version of "Mega Move," an original song created by DIC that first appeared in the Super Mario Bros. 3 series.
Co-Dragons: Kooky and/or Cheatsy in the Saturday morning spinoffs are the ones most likely to be on hand in aiding their dad.
Composite Character: King Koopa, the cartoons' version of Bowser, appears to be a mix of both Bowser and Wart (especially in the Super Show).
Specifically, King Koopa has Wart's crown, green skin and Mooks.
Damsel in Distress: Toadstool 90% of the time in SMBSS; in SMB3 and SMW she took on a more active role.
A Day in the Limelight: All three shows have at least one episode focusing on Luigi - "Quest for Pizza" in SMBSS, "Life's Ruff" in SMB3, and "Mama Luigi" in SMW.
Especially notable is that Luigi is the only one of the four heroes to be in "Life's Ruff".
Dub Name Change: The writers made up their own names for the Koopalings, called the Koopa Kids in the actual show, before the English version of The Manual was final. That, and some of the references Nintendo ended up using would likely go over most kids' heads anyway.
For the Evulz: Koopa's motive for doing the things he does. Examples include turning his sons into giants to kidnap Prince Hugo just so he can turn him into a poodle.
Loud of War: One episode had a group of cute little aliens saving the day by using their kazoo-like noses to hum a tune which drove King Koopa nuts and forced him to flee. The song they sang? The theme of The Legend of Zelda!
This scene features Luigi in Mario's cap and Mario calling Luigi "Mario" in Luigi's voice. In the exact same shot!
The intro meanwhile has some very good animation that one can think it wasn't for the show.
Once per Episode: In each series, the Mario Bros. and Koopa (with the Koopa Kids in the latter two) fight to the beat of a musical montage. Each episode of Super Show, along with a few SMB3 episodes, has a pop music song covered by the cast. The rest of the SMB3 episodes and the entire SMW series have songs specifically written for the shows.
Plot-Induced Stupidity: At no point in the series does Koopa breathefire, even though that's been one of his powers throughout the games. Given the fact that Fire Flowers time out in this milieu, it probably would have made him too broken.
Took a Level in Badass: Princess Toadstool took a more active role in the adventures and was less prone to kidnapping than in the Super Show. She and Toad were even able to use power-ups in the same way as the Mario Bros.
Vague Age: The Koopa Kids in the cartoons are a special case. It's averted with Kootie Pie, who is sixteen, along with Hip and Hop, who are both six. The rest are allegedly in their teens.
Villain Exit Stage Left: King Koopa frequently pulls this off in the Super Show, usually by way of a warp-generating potion (based on the doors to Sub-Con in the American Super Mario Bros. 2), and a few times on the later two as well.
Women Are Wiser: Princess Toadstool is generally the smartest member of the cast.
