Is when she giggles (or laughs in general), since after all, she is known as "The Joy and the Laughter", so during a scene when I hear Bubbles' adorable little voice, it would just put a smile on my face or make me all happy on the inside, like seeing a cute little Puppy! :3 many fans of Bubbles will agree with me, I know that which honestly, I wish especially in the original Powerpuff Girls show, Bubbles could of had just giggled and chuckle a lot, especially if Buttercup could have been less of a jerk to her, who knows, we could of had a scene where she cheers her up like this or laughs with her in a scene that would take a few seconds to roll.
So yeah, tell me what you think if you like Bubbles acting happy since she's a totally better character than the reboot version IMO ;3 @Spacejamstr
