Cow was in a nasty mood. When Duck came along Cow kicked mud in her face.

“Why’d you do that?” asked Duck.

“I felt like it,” said Cow. “And I’m not sorry.”

Little did Cow know that her bad mood would spread to the whole farm. But it does when Cow passes her anger along to Duck who takes it out on Frog who is mean to Bird who upsets Goat who bothers Pig. Until good-hearted Dog turns things around by showing kindness to Pig, turning not sorry into sorry (really sorry). But will that be enough to mend all of the hurt feelings on the farm?
