Thirst Level: 7

Similar to Kuma II and Panda, Amy Rose's thirst goes unnoticed by Sonic. It's honestly pretty sad: she's always by Sonic's side and even fearlessly goes out of her way to help him. Maybe Sonic does notice Amy's advances, and has been collecting rings since 1993 to make her one overly large and priceless one. That's probably not the case, but we're "Team Amy" and we want to see her happy. (Or at least with someone who'll embrace her thirsty-ness with open arms.)
