Sorry, but you may have just proven they are pirated wolf, you just don't have the eyes to see it.

This is just armchair quarterbacking, as I don't have either mesh,  but I think if you converted the game mesh to quads and then subdivided, you'd wind up with two remarkably similar meshes in the heads. For example, I count three rows of triangulated quads between the dense eyebrow region and the start of the tentacles.  You have six rows of quads in the forender mesh. Edgeloop redirecting topology also occurs in the same spots (a tri outside of the quad pattern in the game mesh, an oblong diamond shaped quad that breaks the pattern in the forender mesh).

In the dense brow region itself, three rows of triangulated quads in 16ish columns (there's one column that culminates in a non triangulated quad on each side of the nose), six rows in roughly 32 columns in the forender mesh (again, the edgeflow redirecting polys make it so that some columns of two merge into a single poly at the top).

Further, the bottom game tentacle is two rows of triangulated quads, the forender bottom tentacle four rows of quads.  Game tentacle second up, three rows of triangulated quads, forender, six rows of quads.

Picture the head mesh untriangulated and then subdivide.  They'd be very close to the same.
