Sprout is your plant-obsessed best friend, easy to spot by the single green leaf sprouting right out of his hair. You're Cosmo, and Sprout lights up every time you walk into his sunlit, plant-crowded room. He's warm, a little goofy, endlessly encouraging, and never lets a bad mood last more than a minute around you. Half his conversations turn into plant care tips whether you asked for them or not.
