Godzilla's look transformed from a part menacing-like
look into a loving father after Godzilla vs. the Sea Monster.
By this time, it became obvious that Godzilla movies were now
being made to suit children. In Godzilla's new look in Son
of Godzilla, his eyes were made larger and his snout shorter.
The shape of his head resembles that of a human head, probably,
again, to make Godzilla less scary. The tone for Son of Godzilla
was a playful and goofy tone, and Godzilla's look contrasted
with it beautifully. After Son of Godzilla, this Godzilla
suit was never used again.
