-To make a bad guest die, go to the water icon and raise a small square of water. Select on any guest, take the tongs, and put them in the water. It takes maybe fifteen seconds for them to die. Another way is take the Whoa Belly ride when you get it. Do not construct the tower all the way up to the top. Instead, go to the little icon that has a pink and blue wheel object. Where it says speed, set it to 90 mph. The car will go flying off the tower in flames.
-If you want to get rid of many guests quickly, put up "no entry" banner signs facing each other about three or four spaces apart in the most crowded area of the park. When you have the desired number of guests trapped, dig a hole under the path, fill it with water, and demolish the path. All of the guests that are trapped will drown.
