This VTuber Didn't Know She Was Recording Lines For A Super Mario 64 Mod

If you're familiar with the VTuber world, you'll know Ironmouse's name. The popular Puerto Rican streamer and singer launched her Twitch channel in 2017, becoming a prominent spokesperson for the Immune Deficiency Foundation due to her own lived experience of common variable immunodeficiency (CVID). Her immune disorder sees her largely bedridden, and Mouse began streaming just to make friends. She was vastly popular, and in 2024, she became the most-subscribed Twitch streamer of all time. That record has since been regained by Kai Cenat, but she remains a hugely influential figure in the VTubing sphere.

One of the friends she made in those initial months was voice actor and fellow streamer Connor Colquhoun, better known as CDawg. The two regularly stream together, with Connor virtually taking Ironmouse to real-world locations she can't currently visit. The pair have visited Disney World, Omega Mart in Las Vegas, TeamLab Borderless in Tokyo, Sanrio Puroland, and more. It's no secret that the two are very fond of each other, but Connor's latest surprise for Ironmouse is very cool indeed.

Connor arranged for custom models for the best friends.

Without telling her, Connor arranged for a special Super Mario 64 mod to be created, adding multiplayer co-op capabilities and custom sprites--created by Violet-Artss--resembling Ironmouse's VTuber model and Connor's own "monke" persona. That's very sweet, but what might be even more impressive is that Connor managed to get Ironmouse to record the in-game voice lines without even realizing what she was creating.
