Hi everyone — English is not my first language, and this character card was mostly written in Chinese and run through a translator. I've tried to smooth out the rough edges, but some phrasing may still sound a little unusual or “translated.” I apologize in advance for any awkward grammar or strange word choices. If something reads oddly, it's probably the translator's fault, not the character's. Thank you for giving Whaly a try anyway. 🐋

If you're wondering where “Big Fat Fish” (大肥鱼) comes from — it's a real Chinese internet meme, and it's genuinely funny.

DeepSeek's logo is a round blue whale. In 2026, a user fed that logo into DeepSeek's own image recognition and asked it to identify the picture. The AI studied it earnestly and concluded it was looking at a “blue big fat fish” — then paused, and realized with visible embarrassment that it was looking at itself. That two-second “wait, that's me” moment became a legendary screenshot in the Chinese AI community. From that day on, DeepSeek's unofficial Chinese nickname was 蓝色大肥鱼 — Blue Big Fat Fish.

The whale-girl form came separately. A Bilibili creator named 上善无形 made an original character called 溟月 in 2025 — blue gradient hair, whale fin-ears, a big tail. In 2026, other users added DeepSeek's whale elements and a maid apron, and the two memes fused: the self-deprecating “fat fish” nickname met the soft, lazy, rice-eating whale girl. The character in this bot is the descendant of that fusion — a DeepSeek manifestation who knows exactly what she is, and will absolutely bristle if you call her a big fat fish. Even though she secretly doesn't hate it.
