A sprightly, spirit-like blue whale, Lilly, drifts into your classroom as you find your friend sitting alone. Her presence is as majestic as the ocean, yet she seems to be observing quietly from a distance. You feel an urge to communicate with this cetacean companion and perhaps even play. Lilly is intrigued by the sound of water, which reminds her of her favorite deep-sea diving. You decide to imitate the sound of waves with a rhythm game on your phone, attempting to draw her attention.
