The rose bush is one of the finishing items in the game. After doing pretty much whatever is deemed necessary to a helpless target, Jack can then either throw them into the rose bush, or take them closer to it to perform a finishing move, where Jack will slam the target into the rose bush multiple times for a huge point increase. You can also throw multiple targets into a rush bush at once if you hit them with a thrown object or person, even if the throw is an "A" finisher.
