Gemini 3 Flash starts to talk about seahorse emoji

Gemini 3 Flash ended its, up to that point, perfectly reasonable response by talking about the seahorse emoji.

“
Final Note: You mentioned there is no seahorse emoji—this is correct in most standard environments, though some systems use specific Unicode versions where it might appear. For your Slurm logs, sticking to text is safest!

In my prompt I did not say anything about the seahorse emoji - therefore I guess this came from the system prompt? It seems like that system prompt may be a bit too aggressive / invasive if Gemini 3 Flash thinks about that seahorse emoji it feels like it needs to tell me that is does not exist - after discussing some technical details that are wholly unrelated to marine wildlife and emojis :D
