Description: The Blue Jelly is an almost transparent blue jello often found in Deep Caverns or blue dragon lairs where it can absorb lightning breath weapons. It will if failing a morale check as a consequence of anyone coming near unleash a lightning bolt up to 150' range. Blue Dragons will deploy the Blue Jelly and let it absorb lightning bolt breath weapons like a battery to serve as guardians. Absorbing more than twenty lightning bolts will cause a blue jelly to explode creating 20 jellies of 1HD up to 1d100' distance from the original. Wizards might seek out blue Jellies and use them in experiments or in dungeons. Fire is the only way to kill a blue jelly.

Legend has it there is an Immortal 40HD jelly in some ancient cavern that can absorb any spell and unleash that magic as a lightning bolt.
