Didn’t you see Godzilla vs. The Thing?
It was Mothra, inexplicably called “the Thing”, who saved the world (or at least Japan) from the rampaging Godzilla!
Great movie… including bad guys, good guys, and even two tiny princesses(?) of the Mothra cult, begging for a giant Mothra egg to be retuurned to their island, and singing songs to awaken the dying moth to battle Godzilla.
