As Harry pulled the lid off the terrarium, the plant started reaching upward to try to get out, but as the green liquid fell into the terrarium, the plant seemed to... relax. That's the only description Harry could really put to what he saw the plant doing--it was relaxing. The liquid filled up about a centimeter of the terrarium above the dirt and remained there, not soaking into the dirt. In fact, he noticed that as he poured it, it was much more viscous than he had expected it to be, like a thin sauce or something.

As he watched the relaxing plant, he noticed that it seemed to begin absorbing the green liquid, and as the liquid absorbed into the plant, it grew. Its fleshy, green stem thickened, and its little leaves broadened and grew jagged around the edges. It was like watching one of those time lapse movies of a flower growing but a sci-fi version where the plant was getting kind of scary looking and started reaching out at you. The plant kept growing and growing, sprouting a large, sunflower-like bloom on its top and breaking through the bottom of the terrarium with roots that started reaching for the floor like fractal tendrils. It kept on growing until its roots reached the floor and the plant lifted itself off of its pedestal. Its body was now thick enough to be visibly straining against its glass enclosure until

the plant burst the enclosure, scattering tiny pieces of [url=http://www.hometownglass.com/editoruploads/images/tempered%20VS%20ANNEALED.png]tempered glass[/url] everywhere but doing no harm.

The plant stood before Harry, noiseless (because it had no means of making noise--it's just a plant after all) but menacing, stretching out its new "arms" and slithering along the ground on its tendrils, its "head" looking around for its liberator.
