What do the critters in Sandustry do, and how do I tame them?

Every critter is a small permanent production building that walks. Here is what the official wiki says each one makes, and the two that stop making it if you leave them alone.

Quick answer

The Corraller is the tool: it projects a field that captures a critter and pulls it in, and you release it wherever you want it. The wiki documents five. Lumling produces water and is stated to be the only infinite water source in the world. Voltblub produces small amounts of energy. Redweaver trails Redsand. Voidgrazer converts spent Void Husk back into Void Juice. Shinelet produces decorative light only. Catching one for the first time discovers it in the conservatory, and every capture pays a conservatory ticket.

Steps

  1. Get the Corraller. The wiki describes it as projecting an energy field that captures creatures and pulls them in.
  2. Catch each species once for the record. The wiki states that a first capture discovers that critter in the conservatory, and that each critter captured gives a conservatory ticket — so catching is worth doing even for the Shinelet, which produces nothing but light.
  3. Release a Lumling somewhere with open air. It is the world's only stated infinite source of water.
  4. Sit a Voltblub on a filled Copper Mold if you want its energy captured. The wiki states that as of v0.5.5 its energy is not captured on an Energy Connector.
  5. Give a Redweaver room, and expect to move it. Its own page states it navigates badly and often boxes itself in with the Redsand it just made.
  6. Put a Voidgrazer wherever spent Void Husk collects. It converts that husk back into Void Juice, which is what closes the loop.

Requirements / limits

  • A Lumling produces nothing while it is under water or another liquid, and nothing while it is floating in steam or another gas. It needs somewhere to put the water.
  • More Lumlings means more water. The wiki states the rate scales with the number of critters rather than with anything you build around them.
  • A Redweaver left unattended is stated to end up trapped and unable to produce. This is a documented outcome, not a bug report.
  • The Voltblub's energy is described as a small amount, with no published rate.
  • The Voltblub page contradicts itself: its infobox Produces field reads Water while its body text and tips describe energy. This page follows the body text, states that the infobox disagrees, and does not resolve it.
  • Nothing published says whether critters breed, die, or can be lost.

Common mistakes

  • Dropping a Lumling into the reservoir it is meant to fill. Submerged, it stops.
  • Wiring a Voltblub into an Energy Connector. The wiki states specifically that this does not capture its energy in v0.5.5.
  • Farming Redweavers and walking away. They wall themselves in.
  • Skipping the Shinelet because it produces nothing useful. The capture still registers it in the conservatory and still pays a ticket.
  • Reading the Voltblub infobox and building a water line for it.

Still unverified

  • Does the Voltblub produce water, energy, or both?Single unconfirmed reportThe Voltblub's own wiki page states both, in two different places. Its body text and tips describe energy and name the Copper Mold; its infobox Produces field reads Water. No second source settles it, so the disagreement is recorded rather than decided.
  • How many conservatory tickets does a capture pay, and what do they buy?Not verifiedThe Corraller page states each capture gives a ticket. No published source gives a number or a price list.
  • Are there critters beyond these five?Not verifiedThe wiki's Critters index lists five. Absence from a growing community wiki is not proof there are no others.
