I understand you were eager for fireworks, but seriously. Step up your game, Carn.
There is a hiss as the spark travels along the fuse. It reaches the Powder Keg and everything is silent for a split second. There is a detonation not unlike the flatulence of Zeus, and the resulting shockwave rocks the Squid and the Goldfish like wine corks in a tsunami. Everyone's hair is blown into an interesting 'Swept' style. The mighty borborygmus is heard for miles, with small desert-dwelling creatures emerging from their burrows to see the colossal mushroom cloud.
Koali, of course, is launched skyward by the sheer force of the blast.
Carn and Nathaniel luckily avoid Koali as he crashes down in the dunes, creating a large crater.
