A Vicious Cycle is an episode of Happy Tree Friends, the fifth episode of Internet Season 4, and the 83rd episode overall.
Cub is riding a green metal tricycle in front of his house when the camera dramatically zooms in to the bushes, where the scene quickly changes tonight and Fliqpy, covered in scratches, pops out from the bush. A police siren attracts his attention and he turns to see policemen Lumpy and Disco Bear emerge from the police car, wanting to arrest him. Fliqpy pushes Cub off the tricycle and holds it over his head as an attempt to use it as a weapon. However, before he could do anything, a bolt of lightning strikes the tricycle and instantly reduces Fliqpy to a pile of ashes, which is then blown away by the breeze, leaving the tricycle intact. Cub, Disco Bear, and Lumpy stare intently at Cub's
tricycle when Pop suddenly burst into the scene, carrying a bowl of nachos and several bottles of beer, and he invites the officers in for a snack. As Pop and the policemen are eating in the living room and watching TV, Cub happily rides his tricycle inside the house. However, Pop doesn't approve of Cub riding the trike indoors, so he proceeds to place it back outside, much to Pop's standards and Cub's disappointment. Back inside, as Pop tells Cub not to do such a thing again, the power suddenly goes out. A tricycle bell rings, the light on the bicycle turns on, and it jumps towards Disco Bear, making him scream. Lumpy quickly turns on a flashlight and is shocked to discover blood and skid marks on the couch. He becomes even more sh
Pop goes into the basement and discovers the power box has been tampered with. The cover is blown open, and the switch is down. Pop proceeds to switch the power back on, and everything is normal. Happy and content, Pop climbs up the stairs to exit the basement, however, at the top of the steps, the tricycle stands there. The trike lightly taps on Pop, making him lose his balance. Pop eventually falls down the basement steps, which breaks an arm and a leg, and eventually into the control box, electrocuting him until his head pops off from his body.
Inside the living room, Lumpy is enjoying the blood-covered nachos inside Disco Bear's disembodied head, when all of a sudden the lights turn off again. Lumpy turns on his flashlight once more and sees the tricycle with Pop's severed head on the seat, the bell still ringing. Lumpy, still clutching Disco Bear's head full of chips, runs into the hallway closet to hide. The tricycle slowly rolls by the closet, oblivious to the fact that Lumpy is inside. However, Lumpy blows his cover by making a loud crunching noise as he devours another chip. The tricycle skids to a stop, opens the closet door and attempts to t
