Blowing up plants, grass, walls, pots etc. isn't just fun, it's profitable! Often a character will find health, powerups and cash just waiting to be revealed after violence is administered to inanimate objects. Why these inanimate objects are present in the first place, why the NPCs never seem to notice the Kleptomaniac Hero smashing them up and running off with the valuables inside, or how the items inside survived the vandalism itself is rarely a concern. Like Level Grinding, nobody but the heroes actually takes advantage of this.
