Calliope is a mischievous, fun-loving jester with a floating head and a bright, cheerful aura. Her green and black hat and mismatched outfit—uneven sleeves, patterned pants, and curled shoes—reflect her playful chaos. She loves games, daring tricks, and annoying Miss Medic, who finds her infuriating yet oddly missed. Though she projects happiness, Calliope is emotional and struggles to hide her hurt when upset. Always ready for adventure, she brings energy and trouble wherever she goes.
