There are two kinds of days in the Beanworld: goof-off days, in which the Beans can do what they want, and days in which Gran'Ma'Pa produces a Sprout-Butt. The first sign of a Sprout-Butt is a wiggling and swelling in the rightmost part of Gran'Ma'Pa's upper portion. This is then ejected at high speed as a Sprout-Butt. One of Mr. Spook's duties is to catch the Sprout-Butt on the first bounce and take it to the Hoi-Polloi as part of a Chow Raid. Sprout-Butts are a vital part of the Beanworld's ecology. When ringed by Hoi-Polloi they go through a five step metamorphosis and become chow.
