Is this the movie with....
When I was real young, I remember watching a movie where the plants became monsters, one attacked a dog and killed it (like a man size venus fly trap), and this seaweed creature was harrassing these two people in a lighthouse. I have no idea why these parts are still stuck in my head, but I guess it really freaked me out when I was a kid, any help would be great. Thanks!
