Need help for ripping character model(s) from Spark TEJ 3

[HazegawaM]

After watching a video about Spark the Electric Jester 3, I really love the character named "Fark", and I want to have the 3D models of his many forms, especially the "UltimateFark" model.

I tried both "split" and "merge", but the results are still the same.
Does anyone know if I miss something? Any help you can offer me would be greatly appreciated.
