Help Me Find This Movie

Okay, so I've searched through quite a long list of creature movies, and I still can't find the one I'm looking for.

I've never seen the movie myself, but my dad is adamant that I should watch it. Only, he was too absorbed to see what the name of it was, or even what channel it was on.

He describes it as a movie with these mutant creatures that resemble large frogs. He says that there is the mother "frog" and her many babies, and they are killing a bunch of people on some island. (Sounds like it might be a B movie, or one of those original movies that only appear on tv.)

Anyone seen anything like this?

I had to search...I found this: Frogs (1972)

It was made the year I was born and the date you posted, is my birthday :). Although, when reading the synopsis, I didn't catch anything about a mother frog. But, it is on an island...hope to have helped.
