Go find the thermostat and get the chocolate to melt

From Create Your Own Story

You find a wall panel with three dials on it. One of them might be the thermostat.

Which one do you turn?

• The pretty pink dial with the flowers on it
• The dial currently pointed at a picture of an ice cube, that could be pointed instead at a picture of a fire
• The dial that says 'low' at one end and 'high' at the other end
