The movie is probably 5-15 years old, and may have aired on Disney, Cartoon Network, or Nickolodeon. So there was a group of teens, maybe high or middle school aged, and it was either an evil tree or some plants. Actually, I think I remember the plants getting into the electrical system. When kids put headphones on, and did something on the computer, they’d become glued to it and there were vines connecting from the inside of their ears to the headphones. There may have been like a villain controlling the plants, but I can’t remember. Anyway, please help!
Based on what you’re saying I think it could be TV series My Babysitter’s a Vampire Season 1 Episode 8 “Die Pod”
