Electribbles
A life form of unknown origin, discovered being traded by interplanetary merchants.
Electribbles propegate very rapidly. Given proper enclosed environment and ample food, they can double in population very rapidly.
These furry creatures produce a very high amperage static energy charge which can be harnessed for small appliances and parlor tricks. When aggregated in great numbers however, they can collectively produce large spike of electrical discharge that can effect electronics, repel predators, and stun typical humanoid lifeforms.
