Got an idea for a scenario in my Smash Academy thing.
The Mario Bros set up an obstacle course to teach the kids the finer points of platforming, and Elanore's certain she's got it in the bag since she's based on the Jumpman himself. In fact, she'll probably have the second-best time out of all the students (the best time is out of the question because Bullet exists). And in all fairness her pride is deserved, as she ends up going through the course with just as much ease as the Bros did when they demonstrated it...
...and then she misses the last jump and falls in a pit. It wasn't even a particularly hard jump, she just happened to misjudge the distance a little.
So. She just embarrassed herself in front of her idol after bragging about how easy it would be. And Rumble and Lester are ribbing her about it because of course they are. And somebody happens to point out that she isn't actually based on Mario the way everyone else is based on their counterparts, she just happened to kinda-sorta look like him either by coincidence or because her designer took some inspiration from The Company Mascot.
And, well, she's stubborn, so she tries the course again.
And again.
And again.
She ends up completely obsessed, running the course every chance she gets, filling notebooks that should have her schoolwork and invention ideas with diagrams and calculations to analyze her failed attempts and figure out the solution. Because there are a lot of failed attempts.
It gets even worse over time since the building frustration and stress and the eroding self-confidence and... just about everything else, means she starts messing up on the rest of the course too, until eventually she can't even manage the first jump, let alone finally reach the flagpole. By the end of what would probably be a montage of All That she's become a bundle of nerves who's convinced she can't do anything right, especially not achieve her dream of actually being in a game.
Obviously her friends have been worried about her this whole time, Barney especially, so they've come up with a plan to rebuild her confidence and skills.
...Said plan involves Rumble "kidnapping" Barney and luring Elanore into reenacting the original Donkey Kong arcade game.
Because 1) if she wants to be like Mario, why not start where he started, and 2) from what they can tell the root of the problem is that she started overthinking things after that first failed jump, and if she's focused on saving Barney and kicking Rumble's ass she can't be paralyzed by her calculations and insecurities.
This actually works, reigniting her confidence, and after actually taking care of herself and a quick training montage involving levels from other Mario games she's ready to give the obstacle course one last try.
She doesn't manage to do it as fast or flawlessly as she did the first time, but she still does pretty good, and she actually makes the jump and finishes the course this time.
