There's a great novel called The Boats of the Glen Carrig that features an island populated by malign plants that chase away the sailors that try to camp there. Your creations would be right at home there. Your gallery is one of the best on the site!
Very cool idea. They each even have their own personality, the one on the left looks like it would be kinda goofy, while the middle one looks nasty
I'm surprised Pixar or Dreamworks hasn't done a movie with plants as the characters yet, I'm mean, they've done practically every kind of animal-groups, and even artificial things like toys, robots and cars Guess it would be hard to make a story with plants though
