This was a horror movie, but it’s not letting me change the category. Around maybe 1987 I saw a movie (in color, seemed “new” at the time) on TV about these venus fly trap looking things that crawl up the drains of a house and bite/eat people. One scene was a woman attacked while showering. In another scene a lady is making drinks in a blender and one of the creatures crawls up into the blender and she ends up serving it in the drinks to her friends, who all end up barfing and super sick. At the end you see there is a “mother” creature next door to the house all that was happening in. I had to shower with my eyes open for years because of this thing! I would really like to see it again 😉
It isn’t “Little Shop of Horrors” is it? I haven’t seen it in so long that I can’t remember if any of those scenes match up, but it’s about a Venus fly trap type plant that eats people.
Sounds like Douglas McKeown’s The Deadly Spawn (aka The Return of the Alien’s Deadly Spawn), from 1983.
