Son of Godzilla
I'll try to work with what little I have since this is an extremely poor film to begin with! Not even Shakespeare could salvage much.
A group of scientists are staying on Soleil Island in order to perfect a new weather-alteration device. They are soon joined by Goro, an ambitious young reporter who just drops out of the sky...actually he parachuted in from an airplane. The scientists begin to fiddle with the island's weather conditions, creating first colder, sub-tropic conditions, then they go for hotter weather; however their control slips, and they find themselves taking refuge indoors from a radioactive storm that turns Soleil Island into a giant 200 degree oven.
The radioactivity turns the insects into giant monsters! The giant insects unearth a huge egg. The egg hatches to reveal a baby Godzilla. Papa Godzilla arrives to protect his...er... child. Meanwhile, Goro finds that there has been a beautiful woman on the island all this time; at first the relationship was rocky but in time Reiko warmed up to him. Reiko and Goro befriend young Godzilla too.
Little Minya is just fascinated by his brand-new playmates, but Godzilla has warned his son a million and a half times not to play with those dirty, disgusting humans! At the movie's end, Godzilla defeats the giant spider which almost poisons his son, and the humans on the island cause it to dump a whole bunch of snow. Godzilla and son go into hibernation while the humans make their exit! Please forgive. It was a dumb plot for an even dumber film!
