Picture Time! Box Worms.

These worms have it sorted:
• Cardboard boxes = free
• Heat protecting varnish = free from the local heat protecting varnish fountain
• No pesky marshmallows = free
• Logs for the fire = free. Only the trees paid for it with their life. No one really cares about trees anyway. Otherwise you couldn't live in a wooden house without feeling extremely awful.
• Flames = $250 because they could afford a fancy lighter (since they saved on pesky food!)
• Conversation = free folks - it's free to talk to worms.
• Maths degree for Worm 1 = Worms don't go to university, they are naturally enthused by learning. You wouldn't know that though, as their social skills when it comes to humans is somewhat less than desirable.
• Quality fire-proof-box-by-the-fire time with fellow quality worm = priceless.
