Sow

Sow is a cruel pig who happens to be Cow and Chicken's cousin.

History
Sow was mailed away from her parents for acting so terribly. She went to Cow and Chicken's house for a new place to live. The Parents welcomed her. While there, Cow annoyed her so she hatched a scheme to get rid of her and replace her. She used her appearance similar to Cow to make everyone believe that Cow was responsible for all of the wrongdoings. Her main prank was hanging buckets of milk on doors, so when it opened, the milk fell on the victim. Soon everyone had had enough and they formed an angry mob to set out and destroy Cow. Even Flem and Earl joined in the conspiracy. It was soon discovered that it was Sow, not Cow and Sow was mailed away.

Personality
Sow is a mean, unkind character who attempts to start rumors and destroy anyone whom she doesn't like.
