Opossum Thanatosis: Involuntary Play-Dead Reflex (2D)

A top-down 2D behavior model: watch an opossum forage, bluff-hiss at an approaching threat, then involuntarily collapse into a limp catatonic trance defended by a stink cloud — until it wakes on its own, unpredictable timer.

This 2D companion runs the same threat-driven state machine as the 3D scene — forage, startle, bluff-hiss, involuntary collapse, catatonic trance, gradual revival — from a plain top-down view so the behavior sequence itself, not the 3D staging, is what you're watching.

⚙ Under the hood

A finite state machine drives an opossum through foraging and, when a threat gets close, bluffing then an involuntary limp collapse into catatonia defended by a spreading stink cloud, followed by a slow, uncontrollable revival.
