need tutorial about water simulation combine with animation movement

https://youtu.be/iC594Inuenk

so I need tutorial videos about that scence, because I confuse what kind simulation i shall use, it’s should fluid simulation or ocean simulation because if I use the fluid simulation the texture or material isn’t seem realistic or look alike swamp but if I use ocean simulation I don’t know how to make the character floating on the water and how to simulate the splash. NB I just use BLENDER internal render

thanks and sorry for bad english :):D:D
