IShowSpeed and Kai Cenat channel Mario & Luigi as they reveal wild Super Mario Bros setup

When it comes to chaos, laughs, and iconic duos, IShowSpeed and Kai Cenat never disappoint. This time, the internet couldn’t get enough as the two streamers dressed up as none other than Luigi and Mario to unveil their Super Mario Bros-themed setup, and yes, it was as wild as it sounds.

The moment they showed up in full costume, Speed rocking Luigi’s green hat and Kai donning Mario’s red cap, fans instantly knew they were in for an unpredictable ride. The energy was unmatched, and the setup itself? Pure nostalgia with a twist of Gen Z chaos.

Super Mario Bros setup goes viral

The post quickly made waves online, and it’s not hard to see why. The visuals alone, Speed awkwardly navigating a green dress-like costume, and Kai fully committing to the red jumpsuit were already enough to spark a reaction. Add to that a room decked out in Super Mario graphics, props, lights, and props flying left and right during the stream, and it was content gold.

Fans were quick to jump in with reactions that ranged from confused to cracking up. One user questioned Speed’s outfit with a hint of sarcasm:

A user hilariously asked:

And then there’s always that one viewer who breaks it down with logic and laughs. In this case, Kai’s role as Mario wasn’t up for debate:

A user noted:

"Of course Kai is Mario 🤣 he the short one."

From there, it was just a stream of playful commentary. The pair’s reputation for turning their room into a chaotic mess mid-stream didn’t go unnoticed either.

One viewer joked:

"We already know that room is going to be a disaster at the end of the stream"

Then came the wholesome takes, the ones that acknowledged the duo’s chemistry without overthinking it:

As another fan simply said:

"The real super Mario brothers"

And of course, the marketing-savvy ones online who always wonder what goes on behind the scenes had to chime in too:

A user took to Instagram and speculated:

"i wonder how much nintendo pays them for this"

Speed and Kai are two of the most explosive and unpredictable content creators in the game right now. With millions of followers between them, everything they do, from reacting to viral videos to pulling off full-on themed streams like this one, is instantly spotlighted.

Their personalities clash and blend in the best way: Speed brings the over-the-top energy and unfiltered chaos, while Kai balances it with smart jokes and that classic “I knew this was coming” vibe. It’s what keeps fans tuning in.

This Super Mario Bros stream wasn’t just cosplay or a gimmick. It was a blend of internet culture, gaming nostalgia, and influencer marketing done right, intentionally or not. And the fact that it sparked such a wave of reactions shows that they nailed it once again.

As the stream wrapped up (with the room in total disarray, obviously), one thing was clear: Whether they're pretending to jump through pipes or shouting “It’s-a me!” at the top of their lungs, Speed and Kai know exactly how to put on a show.
