People sometimes ask where I get my inspirations/material from. Simply put, about 80% of it comes from real life. Case in point, the cafeteria where I get my lunch has flavor syrups you can add to soft drinks/tea/juice. You can also get soda water/club soda/seltzer water straight from the dispenser. So I mixed together caramel flavored syrup and soda water. It made me think about the idea of a caramel drink, and then just straight melted caramel, and I knew which character to assign that thought too. Also, caramel flavored soda is actually very... ah, unique.
