Flammable Goo Balls

Red goo balls are flammable, and when one is connected to another ball, its line is brown. You don’t want these balls to catch on fire; keep them away from flames or they’ll pop and break. Build around a flame if you need to get through it, or in certain cases, use them to your advantage and start a chain reaction to drop nonflammable goo balls in the direction you need to go.
