Voltblubs generate free electricity, which can be harvested by surrounding them with a Critter Fence. In Update #3, you can pet them to temporarily boost their energy output!

What the Wiki
currently says.
Voltblubs are passive subterranean electrical critters native to deep underground cavern biomes in Sandustry.
A Voltblub passively accumulates ambient electrostatic charge and discharges localized electric pulses every 4 seconds.
Engineers can enclose Voltblubs within insulated Critter Fences to capture periodic pulse discharges with nearby Kinetic or Logic Wire sensors.
Voltblubs do not attack the player or factory buildings, but uncontained critters can trigger erratic signal interference on unshielded logic networks.
Subterranean Fauna & Husbandry
Voltblub Habitat, Containment & Petting Mechanics
Introduced in Update #3, the Voltblub is a subterranean electric critter inhabiting deep caverns. Neutral by nature, Voltblubs emit periodic bio-electrical pulses and can be corralled using Critter Fences.
| Critter Attribute | Specification | Husbandry Protocol |
|---|---|---|
| Natural Habitat | Deep Underground Caverns | Spawns naturally in dark, crystal-dense subterranean biomes. |
| Containment | Critter Fences & Doors | Keep pens sealed with Critter Fences to prevent wandering into hazardous Lava. |
| Interaction | Petting Mechanic | Petting a calm Voltblub stimulates electrical discharge and creature happiness. |
| Logistics Role | Passive Bio-Charge | Position corrals near battery charging hubs for supplementary localized current. |
⚠️ Thermal Safety Warning
Voltblubs are sensitive to open Lava and extreme radiant heat. Ensure creature enclosures are built with adequate buffer distance from smelting forges and active burner belts.
