Locap
found only in the deep oceans of the planet Naboo, this strange form of plantlife burrowed into the soft rock of the planet's core and extracted plasma. As the locap digested this plasma, it converted it into a safe form of energy. The Gungans learned how to obtain the digested plasma from the locap and used it to power their underwater cities and their shield generators. The locap plant can grow to incredible sizes, and the Gungans often built their bubble cities along the branches of individual locap growths.
