## Summary

A French agency, Mementum, has filed a lawsuit against Do Big Studios in a Californian federal court over the inclusion of the AI‑generated character Tung Tung Tung Sahur in the Roblox game *Steal a Brainrot*. The character, an anthropomorphic wooden drum, was created by Indonesian teenager Noxa using OpenAI’s image generator, requiring seven prompts and about 15 minutes of interaction. Mementum, which represents the character, demanded that Do Big Studios cease using it; the studio removed the figure, attempted negotiations, and then sued.

The dispute highlights a broader legal uncertainty. A 2025 U.S. Copyright Office report stated that works produced solely by AI are not eligible for copyright protection, but it left open the possibility that substantial human creativity could qualify a piece for protection. If the court rules the character unprotected, creators who rely on AI tools may find their outputs vulnerable to copying, while a protective ruling could shift demand toward AI‑generated content over traditional creative services. The outcome could reshape how the creative industry approaches AI‑assisted production.

## Key points

- Mementum sued Do Big Studios in a California federal court over the AI‑generated character Tung Tung Tung Sahur.
- The character was created by Indonesian teen Noxa using OpenAI’s image generator with seven prompts in 15 minutes.
- A 2025 U.S. Copyright Office report says purely AI‑generated works aren’t copyright‑eligible, but human input may change that.

## Why it matters

The case could set a precedent on whether AI‑generated characters receive copyright protection, influencing creators, studios, and the expanding market for AI‑driven content.
