S02E05 Giggles

Ariel finds humor in everything, even the serious moments, which leads a sorcerer blowfish to cast a spell on her. Now, every time she laughs, it triggers seaquakes. Frustrated by this unexpected consequence, Ariel eventually confronts the blowfish and shows him the true power of laughter. Through their interaction, she teaches him that joy can be uplifting rather than disruptive.
