Sandustry Critters Guide: All Creatures, Capture Tools & Uses
Quick answer
Sandustry creatures are officially called Critters. Capture and contain them with Corraller/Critter Fence systems, then pet them for temporary capability boosts in v0.5.6.
Quick answer
Sandustry “creatures” are officially called Critters. The current official roster lists Shinelet, Lumling, Redweaver, Voltblub, and Voidgrazer. Use the Corraller to capture critters and Critter Fence style containment when building around them. In v0.5.6, moving over a critter pets it, makes it happy, and temporarily boosts its capabilities.
Do not treat critters as decoration only. Some are connected to useful resource behavior, and the Beginner's Guide specifically notes Lumlings as a possible Water source. Update #3 also boosted Voltblub Energy output, so re-test older power builds before assuming old rates.
All known Critters
| Critter | Current known role | What to verify in game |
|---|---|---|
| Shinelet | Official critter roster entry | Location, capture behavior, and output |
| Lumling | Mentioned as a Water source | How many are needed and how fast Water appears |
| Redweaver | Official critter roster entry | Location, capture behavior, and factory use |
| Voltblub | Energy critter with boosted output in v0.5.6 | Current output rate and containment spacing |
| Voidgrazer | Recycles Void Husk into Void Juice | Containment and access to Void Husk |
This page is intentionally conservative: it tracks verified names and safe setup rules first, then can split individual critter pages when GSC shows demand for Lumling, Voidgrazer, Redweaver, Shinelet, or Voltblub.
How to capture and contain Critters
- Unlock the Corraller through Research.
- Locate the critter and clear a safe path around it.
- Capture it before building the production cell.
- Create a contained enclosure with enough room for movement.
- Keep factory outputs reachable; a critter stuck behind walls is usually useless.
- Label the enclosure by critter type so later experiments do not mix behaviors.
Best early uses
| Goal | Critter angle |
|---|---|
| Water support | Test Lumlings in a contained basin |
| Void Juice recovery | Keep Voidgrazer near Void Husk output |
| Research documentation | Record location and behavior before moving the critter |
| Factory safety | Keep critters away from open Lava, fire, or uncontrolled falling material |
Common problems
“I searched Sandustry creatures but cannot find them”
Search both names. Community posts may say “creatures,” but the official category uses Critters.
“My critter does nothing”
Check whether it has access to the material or space it needs. Voidgrazer, for example, matters when it can reach Void Husk. On v0.5.6 or newer, move over the critter once to pet it, then watch whether the temporary happy state changes the behavior you are testing.
“The critter escaped”
Do not build the enclosure while the critter is already loose in the factory. Capture first, then release into a finished containment cell.
