Beloved Mario RPG hides a secret "'Toads ramming each other rapidly' test room" where "talking to Peach causes the Toads to ram each other rapidly"

Have you ever wanted to see Mario's Toads ramming each other rapidly? You'll get no kinkshaming here, because somebody at Nintendo was right there with you. The 2019 3DS remake of beloved RPG Mario & Luigi: Bowser's Inside Story features a hidden, unused room where you can make a group of Toads, er, ram each other rapidly.

Here's how prolific Mario trivia hound Supper Mario Broth explains it on Bluesky: "Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey contains an unused 'Toads ramming each other rapidly' test room, containing Peach and three pairs of Toads. Talking to Peach causes the Toads to ram each other rapidly."

This discovery comes from a six-month-old YouTube video with 200 views, posted by the appropriately-named Mario & Luigi Scrapped Maps. Using modified save files, they explore a host of unused rooms buried in the game files. Many of them seem to be debug areas, offering ways for developers to quickly test various in-game functions.

The "Toads ramming each other rapidly" room seems to be an animation test room, where talking to Peach activates various movements from the Toads. First, they run backward and jump forward. Then a matched pair of Toads jumps back and forth across from each other. Then, finally, it happens. The Toads begin to ram each other rapidly.

It all sounds like a euphemism, but you can put your own imagination to work in determining what it's suggestive of. Certainly, you'll find a lot of wiggling eyebrows among the responses to Supper Mario Broth's post, particularly with the thought that it's Princess Peach herself making this all happen. Well, who's to stop Mushroom Kingdom royalty from deploying her loyal retainers however she sees fit?

All I'm saying is that the best Mario games could each use a little more in the way of Toads ramming each other rapidly.
