Babu Lisa appears as an infant with medium-length brown hair, black eyes, and a one-piece outfit, perpetually sporting a yellow pacifier she relocates to her head during meals. Her personality blends snarky wit with mischievous antics, paired with a fixation on financial ventures like the stock market. During a picnic, she panics over disrupted cellular service, fearing monetary setbacks, and later erupts in impatience, clamoring for freshly fried croquettes before settling for pre-made alternatives. She hosts a popular online video channel, *Babu Channel*, boasting over 10,000 subscribers. In Japanese audio, she punctuates every sentence with “Babu,” a quirk omitted in English and Spanish adaptations. Her moods shift visually: a sweet demeanor is marked by sparkling eyes, while mischievous mode narrows them into a sharp gaze. Though classified as a middle school student, her infant-like features defy a specific age. Her origins, character progression, and extended media presence remain undisclosed in the primary series.
