Synopsis:
A new discovery on Rann allows food to be enlarged to giant size. An unforeseen side effect however causes fireflies which eat the food to grow as well. The enlarged light-sacs of the fireflies cause fires to start, but the Ranagarans develop a way to neutralize the effect.

When a Zeta Beam brings a flame being to Rann instead of Adam Strange, he contacts his fellow beings and together they enjoy their new existance on Rann. However the flame beings are a hazard to the residents of Rann. Riding the giant fireflies to get close to the flame beings, Adam Strange disables them with carbon dioxide.
