Growzers were domesticated creatures that lived on the world of Celwis. Lakphro and his relatives had several growzers which they utilized for managing their Yubal livestock. Slobber was the name of one particular growzer belonging to them, and it had been taught to respond to the noise of a jacket sealer. Growzers were also used as a basis for various expressions, such as "son of a growzer" and "Some days the growzer you are, and some days the growzer's son you are."
