Everyone knows you're the scarediest. Bubbles is sick and tired of being treated like a baby! So, what if she squeaks when she speaks? And if she's a little afraid of the dark? Does that mean that Bubbles isn't hard-core like Blossom and Buttercup? No way! Villains better beware, 'cause Bubbles has something to prove - and this sister is doin' it for herself!
