Potential obstacles for my game

My game setting is based of a fire fighter bear puts out fires. Maybe he rescues people. So the obstacle could be an arsonist which anthropomorphic animal. I also like to create plants and things that cause fire.

Black bear ( an arsonist) — He drop throw bombs on towns.

Tabaco bear — He cause fire unconsciously, he is weak but appear very often. The fire fighter need to put water on him.

Fire Flowers — They grows everywhere as weed and creates fire. The main character can’t touch them, so need to action as jump and avoid them or kill them.
