Lanolin Sheep is a U.S. Acres character and the second-to-last introduced main character in the strip (before Bo). Lanolin is responsible and hardworking, but she is also the polar opposite of her brother: mean, rude, loud, disagreeable and short-tempered, though she tends to deny this. She and Bo usually disagree over petty things, although there are times when the two can agree, usually when it comes to helping the gang out. She is very blunt in her speech and is rarely in a good mood.
