okay, so when I was younger, I watched a weird movie. It had these 2 monsters, 1 red, 1 blue, that were invisible but became visible when there was a light source near em. I remember one scene of the movie near the end where a village built a trap for it and they tried to lure em in... I also remember at the end it showed a scene of baby versions of them. I really liked this movie but I can't remember the name of it for the life of me. The monsters were kinda like beasts that impaled people with there tails I think but I can't even find a pic on google images... it would be great if someone knows this movie that could help me out.
