Puft

The Puft is a yellow, three-eyed critter commonly found in polluted environments. It ingests Polluted Oxygen and excretes Slime with 95% efficiency, making it one of the earliest renewable ways to turn contaminated air into a useful ranch product. That Slime can then be processed into Algae or used directly for Dusk Caps, so Pufts are often part of a slime-to-resource loop rather than an end product on their own.

Pufts are non-hostile and will flee when attacked. They search for nearby breathable material to inhale, and in normal ranch conditions they usually inhale in bursts, then rise toward the ceiling and excrete their output every few seconds. Their conversion rate is much better when their movement is restricted; if they spend too much time wandering or floating around the pen, production drops noticeably. They also will not produce droppings if they cannot rise upward, but this can be worked around by using a Pneumatic Door as the roof, since it blocks them from escaping while still allowing output to pass through.

A basic Puft ranch usually keeps liquid on the floor of the enclosure so the Slime remains in solid form and can be collected cleanly. Polluted Water on the floor is enough to off-gas Polluted Oxygen and feed the Pufts, and pairing them with Morbs is effective because Morbs continuously produce the same gas Pufts consume. Sorting eggs into dedicated pens is important for maintaining the desired morph line. Puft eggs take 15 cycles to hatch outside an Incubator, or 3 cycles if Lullabied.

Pufts can lay all four of their morph eggs depending on age and whether a Puft Prince is nearby. The general trends are:

• The chance of laying a Puft egg decreases over time no matter what they are penned with.
• If not penned with a Puft Prince, the chance of laying Puft Prince eggs increases over time.
• If penned with a Puft Prince, the chance of laying Dense Puft and Squeaky Puft eggs increases over time.

The Puft Prince is functionally similar to the base Puft, but it can breathe all three gases and only excretes 10% of the inhaled mass. It is mainly useful as the breeding partner that unlocks Dense Puft and Squeaky Puft production. Puft Princes themselves only lay Puft eggs in practice, since their own Puft Prince egg chance disappears before it can matter.

Dense Pufts require Oxygen and produce Oxylite at 95% efficiency. This makes them useful for renewable Oxylite production, especially since the output can be used as a rocket oxidizer. Squeaky Pufts require Chlorine and produce Bleach Stone at 95% efficiency, which supports Waterweed farming and Hand Sanitizer refills. Both variants follow the same morph rules as the base Puft, with a Puft Prince steering the egg distribution toward the desired morph.

The main practical challenge with Puft ranching is handling their habit of floating upward while their outputs need to stay accessible. Stable design and atmosphere control matter more than raw space, especially for Chlorine-heavy Squeaky Puft setups or Oxylite farms that rely on controlled Oxygen supply.
