The Johnson and Elliot Families Are United By Marriage.
There's a strong resemblance between Stan Johnson in this movie and Lt. William Elliot from Cave Women on Mars. Give the relatively small population of Phantom Lake, it seems likely the Elliots and Johnsons are related.
The Creature from Terror from Beneath the Earth is an alien - not a mutated bat.
It was never conclusively shown that The Creature was a mutated animal and an alien resembling The Creature is seen in the Bar Full of Aliens in Destination: Outer Space.
