Thorny Devil Skin Water (2D)

Top-down companion to the thorny devil's capillary water-collection: the lizard walks to damp patches and passively drinks through its skin — no muscle, no pump, just a groove network that wicks moisture toward its mouth.

This 2D companion follows the same passive mechanic as the 3D scene: moisture that touches any point on the thorny devil's skin travels along a microscopic groove network between its scales by capillary action alone, no muscle or pump involved. Walk it to a damp patch (or click one to send it there) and the moisture bar next to that patch drains while its drop count climbs; trigger a predator threat and watch the spiky false "hump" on its neck light up as a decoy while the real head tucks away.

⚙ Under the hood

Top-down Canvas 2D lab: a state-machine lizard seeks the nearest active damp patch or ant, drinks via a capillary-uptake rate scaled by a dew-sensitivity slider and the current time-of-day preset, and can trigger a decoy-hump defensive response on demand.

Why doesn't the lizard use muscles to pump water to its mouth?

It doesn't need to — capillary action alone (the same effect that pulls water up a paper towel) is enough to move moisture through the microscopic grooves between its scales, all the way to the corners of its mouth.

What does the false "hump" actually do?

It sits on the back of the neck and looks like a second head. When a predator threat is detected, the real head tucks between the front legs while the spiky hump takes any strike instead.

Why does dawn increase moisture collection?

Cooler, humid dawn air condenses dew directly onto the skin and sand, giving the capillary network far more moisture to wick up than the dry heat of midday.
