Desert Tortoise Water Memory Lab (2D)

This 2D companion models the desert tortoise's water budget as an explicit resource loop instead of a scripted forage animation: a bladder reserve drains with drought and metabolic demand, and can only be refilled at one of a handful of fixed rock basins that fill after rain and dry out again over the following day or two. Whether a tortoise reaches water in time depends on its own spatial memory of which basins have paid off before — a genuinely noisy estimate that gets corrected the moment a remembered basin turns out dry — rather than on omniscient pathfinding to a randomly regenerating resource.
