Bubble is usually kindhearted and happy, but when she is afraid of something, she will try and prevent it from happening (e.g. Pencil telling Lightning to shock someone in "Getting Teardrop to Talk"), which occasionally has consequences. There are times when Bubble has fits of eccentricity like "Rescission" and "The Long-lost Yoyle City" where she makes bizarre faces and movements for a short time. You Can Use Those, No Credit Needed, But I'll Appreciate if You Did.
