Hotbug (higher-res)
   Hotbugs at DM's Lair


The hotbug is similar to the lightning bug in many respects, but this variety produces incredibly heat. When gathered into a jar, the combined warmth of multiple bugs is enough to be used as small portable oven or an alternative heating device.

Hotbugs are one of the prime components needed to properly heat the famous Frobozzian Magic Cocoa of Concentration.
