I can’t remember if this was a Disney channel movie (I tried to research them but didn’t see the one I’m looking for) I saw when I was a kid sometime in the 90’s. It about I think this boy whose mom disappears and his dad remarries this woman. He never likes her. He and his friends uncover more and more about her and find a cave of cocoons filled with people in them. One of them had his mom in it. The woman was an alien/monster in disguise and would save people in cocoons to eat them later. I think someone is killed in a shower. Does anyone know anything that could help??
