In a year of goofy monster movies, this is second rate.  I blame part of that on the English dubbing.

As usual, Japanese scientists travel to a tropical island to do some questionable experiments and come upon an infant monster.  Of course, they must take it home, largely at the insistence of a greedy promoter.  Mommy and Daddy Gappa come to the rescue and all but destroy Tokyo in the process.

The movie is in color but I liked this still.

This combines a bird-lizard monster a la The X from Outer Space and the sentimentality of Son of Godzilla.  It lacks the  inadvertent hilarity of both, though.
