Imagine a coffee dragon…
If you leave coffee alone, the coffee dragon is likely to come. They steal left over cups of coffee, so always rinse out your cup.
It has brown scales a mix between mocha and light coffee. And it hates cold coffee. Iced coffee annoys it. Its inner scales over the stomach are red generally and it technically would be called a bronze dragon, although muted a lot.
If they find cold coffee, they will heat it up probably causing a house fire. So if you’re leaving your coffee alone, you better keep it warm.
