As the flea continued to gnaw away inside your skull, your eyes fixed on your new tail as the urge to chase your tail grew stronger with every passing moment. Despite your human intellect screaming at you to resist, your body began to move in a way that felt eerily natural.
The room around you blurred as you succumbed to the instinctual dog-like behavior, the thoughts of disbelief and confusion fading away as the desire to chase and catch the elusive target grew more intense.
Standing on all fours, you took off chasing your tail wagging in the air as you circled the messy room, panting with excitement. Your movements grew more erratic as the flea's influence spread, the boundaries of human and animal blurring into an odd yet mesmerizing dance.
Each time you'd almost catch your tail, the flea would make it slip away, leaving you eager for more. Your mind raced with simple canine pleasures: the scent of the floorboards, the feel of your own breath in your nose, the thrill of the chase.
You didn't know how long this went on, but eventually, the flea's biting grew less frequent. The madness of the pursuit began to subside, leaving you panting and exhausted in the center of the room. With a final shake of your head, you collapsed onto a pile of discarded blankets, feeling more like a dog than ever before.
