There are several other uses for a Fire Bug besides burning sugar cane. I've already asked a question to determine these but one I know of is the ability to burn Spider Webs blocking your path in a cave.
A Fire Bug will sometimes explode upon use when using it on Sugar Cane. I was wondering if the Fire Bug also has a chance to break when performing other activities or can it only happen when burning the Sugar Cane?
What else can a Fire Bug be used for besides burning Sugar Cane?
