But isn't that gif from Godzilla vs. SpaceGodzilla?
I have not seen Godzilla vs. SpaceGodzilla ... only Son of Godzilla.
from wiki ...
Son of Godzilla, released in Japan as Kaijū-tō no Kessen Gojira no Musuko ... is a 1967 Japanese science fiction kaiju film ... Continuing the trend of shifting the series towards younger audiences, the film introduced an infant Godzilla named Minilla.
(middle of plot description)
The baby Godzilla, named Minilla, quickly grows to about half the size of the adult Godzilla and Godzilla instructs it on the important monster skills of roaring and using its atomic ray. At first, Minilla has difficulty producing anything more than atomic smoke rings, but Godzilla discovers that stressful conditions (i.e. stomping on its tail) or motivation produces a true radioactive blast. Minilla comes to the aid of Reiko when she is attacked by a Kamacuras, but inadvertently awakens Kumonga (Spiga in the English-dubbed version), a giant spider that was sleeping in a valley. Kumonga attacks the caves where the scientists are hiding, and Minilla stumbles into the fray.
Kumonga traps Minilla and the final Kamacuras with his webbing, but as Kumonga begins to feed on the deceased Kamacuras, Godzilla arrives to save the day. Godzilla saves Minilla and they work together to defeat Kumonga by using their atomic rays on the giant spider. Hoping to keep the monsters from interfering in their attempt to escape the island, the scientists finally use their perfected weather altering device on the island and the once tropical island becomes buried in snow and ice. As the scientists are saved by an American submarine, Godzilla and Minilla begin to hibernate as they wait for the island to become tropical again.
