Passed the validator: real scale, rests on y = 0, front faces +Z, deterministic.

Use it

Code for the specimen as it is set up above; it follows your knobs.

JavaScript
import { createAsset } from 'https://gaitkit.com/cdn/tentacle-lurker.mjs';

const tentacleLurker = createAsset();
scene.add(tentacleLurker);                      // rests on y = 0, front faces +Z

// 'tentacle_0' pivots on its hinge: -12° to 12° around x
tentacleLurker.getObjectByName('tentacle_0').rotation.x = THREE.MathUtils.degToRad(-12);

More in the docs; agents can fetch all of this through MCP.

Knobs

KnobTypeValuesDefaultWhat it does
tentaclesrange4 to 8, step 16How many tentacles grow from the base, spread evenly around it. 4 = sparse and readable; 8 = a writhing crown.
skinchoicebog abyss flesh ashbogSkin colour: bog (olive swamp green), abyss (deep-sea purple), flesh (raw pinkish red, the most visceral), ash (cold grey-teal, cave or ruin dweller).
eyeColorchoiceamber red green violet iceamberIris colour of the big eye; it glows this colour at night. amber, red (hostile), green (toxic), violet (arcane), ice (pale cyan).
sizerange0.4 to 3, step 0.051Uniform scale. 1 is about 1.9 m tall; 0.4 is a knee-high pest; 3 is a 6 m pit boss.
seedrange1 to 99, step 13Reshapes the lumps and spots of the pod and gives each tentacle its own length, curl and rhythm. Any whole number gives a new individual.
