Gorgo #2

When the British electrify the waters off Ireland, Gorgo and his mother head west to America. Gorgo is attacked after it fouls the trans-Atlantic telephone cable and gets incapacitated in a sandpit while his mother is sleeping. When she wakes up and finds the baby missing, she attacks New York City. The world's weakest Hydrogen bomb is dropped on her, which fails to kill the monster. Gorgo eventually escapes from the sandpit and reunites with his mother but gets wounded by cannon shells loaded with a nerve agent. His mother scoops him up and returns to the ocean where they both go to sleep.
