These small oozes were created by wizards to glide harmlessly through households and work stations, cleaning surfaces perfectly without disturbing precious belongings. Their engineered resilience, drive to feed on organic material, and ability to understand commands make them highly sought-after as familiars for those of a certain class or profession. Domestic ooze husbandry is a closely guarded secret and they have been bred without the ability to reproduce by budding. Those who want another ooze (or a replacement) must find a breeder to acquire one. Oozes are ageless and neither breathe nor sleep. Domestic oozes are engineered to be docile and nonlethal, and only those who are not evil-aligned can form a Familiar Bond with them. Only rarely do housepets go missing after crossing the ooze's pristinely clean path, and it is usually accidental when they do. There are 4 domestic ooze morphs:

The domestic ooze can serve as a familiar, forming a magic, Telepathic Bond with a willing companion. While the two are bonded, the companion can sense what the ooze senses as long as they are within 1 mile of each other and it will follow a mental commands the companion gives it that the ooze is physically capable of accomplishing. The ooze acts on its companion's initiative.

Gelatinous body: The ooze can move through gaps at least 1 inch wide without squeezing. Creatures can enter the cube's space, but those that do are subject to the cube's Engulf ability and have disadvantage on the saving throw to avoid it.

Spider Climb: The ooze can climb difficult surfaces, including upside down on ceilings, without effort.

Actions

Pseudopod: The ooze can extend a pseudopod to interact with an object or creature within 5 feet of it.

Mobile Cleanse (Organic): The ooze moves up to its movement speed, consuming and dissolving nonliving, organic spoilage in a line up to 1 foot wide, completely cleaning a surface as it glides along. It doesn’t dissolve bone and can't dissolve inorganic materials like stone or metal. It can clean a flat 5' x 15' surface in 1 minute. It leaves no residue behind whatsoever.

Engulf: The cube moves up to its speed and enters a Tiny creature's space. The creature must make a DC 10 Dexterity saving throw. On a successful save, the creature can choose to be pushed 5 feet back or to the side of the ooze. A creature that chooses not to be pushed suffers the consequences of a failed saving throw. On a failed save, the cube enters the creature's space, and the creature takes 2 (1d4) Acid damage and is engulfed. The engulfed creature can't breathe, is restrained, and takes 2 (1d4) Acid damage at the start of each of the cube's turns. When the cube moves, the engulfed creature moves with it. An engulfed creature can try to escape by taking an action to make a DC 10 Strength check. On a success, the creature escapes and is deposited on a side of the cube (the creature chooses which side). The cube can hold up to 2 Tiny creatures in its body at a time.
