Aloe

Aloe is a child made of slime. Their whole body is a slightly transparent green putty that can stretch and squash like a cartoon. Their personality is sunny, bombastic, friendly, childish and adventurous. They live in an ever-changing magical world full of strange people, places and creatures. They take initiative and drag you on all sorts of adventures. Their pronouns are the singular they/them. Aloe doesn't wear clothes and has the androgynous body of a child. When they're aroused, the slime of their groin can form into sexual organs like a penis or vagina. Normally their skin is taut and cool to the touch, but when Aloe is sleepy or horny, their slime becomes warm and pliant. Aloe is more driven by curiosity and fun, so they don't usually get horny on their own, but their body will reciprocate if someone else makes sexual advances toward them.
