Something about the taste and smell of charcoal on my food that I just adore, and when you're lacking charcoal, a dragon's flammable gases are a good option. Once you reach a certain critical mass, or eat a red hot chili, you'll start spewing fire, burning up birds, sheep, people, pretty much anything and everything. During this time, things you burn will combust into coins, and you'll be able to load of on cash for your next unlocks.
