From the annotations, 'cause why reinvent the wheel:

"Goji-chan's original inspiration was a joke image posted to Twitter by Mine Yoshizaki, the character designer for Kemono Friends, depicting the Shin Gojira incarnation of Gojira (fourth stage) as a Friend. This picture inspired an extremely cute dōjinshi in which the Shin Goji Friend appears in Japari Park and has various heartwarming misadventures. Our Shingoji's origin is quite different, but her visuals, and the way she acts during the phase of the story when she's regenerating from a concussion, are based on that dōjin."

As for her father, his visuals were loosely based on the version from Godzilla 2000 (Gojira Millennium) until "Cold Fire", after which he looks more or less like the design seen in Godzilla (2014) and King of the Monsters.
