Can someone add swimming animations to this NAGA model?

[Kolossoni]

I found this custom naga model from this random website, but the model lacks a "swimming" sequence like most naga models. Can somebody add them for me? I don't know where she's from though. She doesn't look like a WOW model either...

P.S. I'm NOT demanding anything. Therefore, I don't mind if nobody's up to do this. But, if someone does volunteer, I'll REALLY appreciate it though!
