The Pajanimals have had fun building pillow and blanket mountains in their room, but things have become a great mess. Their mother tells them to clean up, but they decide it's not worth it since things will just get messy again. That night, Mom is annoyed with them and Cowbella can't find her Princess Lucy unicorn. They visit the Land of Build-It, where Hank and Frank help them to see why cleaning up their messes is important.

Sweetpea Sue and Cowbella are excited that grandma has sent them each a real teacup that she had when she was a kid. Sweetpea's is red and Cowbella's blue, but Sweetpea is sad when hers arrives broken. Apollo suggests that Cowbella could share her teacup, but she doesn't want to, which makes Sweetpea angry. That night the Pajanimals visit the moon, and Sweetpea tells him about the problem. Cowbella realizes that she feels sad because Sweetpea is sad, and the Moon tells her that as family, they care about how each other feels. Cowbella decides that she's going to give Sweetpea her teacup to make her feel better.
