The Cobras Secretary.
The Cobra - Not an actual Cobra, rather a fungus that has evolved over time to resemble a cobra, this keeps smaller animals away.
The Secretary - The Secretary bird is an Africa bird of prey that hunts on the ground and bludgeons its prey with its long legs; this bird however, has confused this fungus for a real snake.
The impact sound was me hitting myself in the head with a foam roller
