A Vicious Cycle

A Vicious Cycle is an episode of Happy Tree Friends, the fifth episode of Internet Season 4, and the 83rd episode overall.

Plot
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 to night 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. Cub, Disco Bear, and Lumpy stare intently at Cub's tricycle when Pop suddenly bursts 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 skidmarks on the couch. He becomes even more shocked to discover Disco Bear's severed head on the coffee table, with his brain exposed, and nachos embedded all over. As Pop leaves the scene, Lumpy closely examines the severed head.

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 tackle Lumpy, but Lumpy tries to fight back by holding the pedals. Unfortunately for the moose, the tricycle spins around and hits Lumpy's face five times, decapitating and killing him.

Sometime later, in the blood-covered living room, Cub contently rides the trike indoors once again. Just before the episode ends, Cub rings the trike's bell, which is stuffed in an eyeball.

Goofs

 * 3) The design of Flippy's beret changes three times.
 * 4) When Disco Bear steps out of the car, he is shown much taller than he is supposed to be.
 * Cub, Disco Bear, Lumpy and the police car are nowhere to be seen when the lightning strikes Fliqpy.
 * 1) Upon close observation, Fliqpy is already burnt to ashes before the lightning strikes him. S4E5 Already burnt.png
 * 2) Lumpy's antlers change places a few times.
 * 3) When Pop walks out of the house there are three beer bottles in the bucket. When everyone goes inside, Lumpy is holding an extra bottle (It could have been an extra though).
 * 4) Pop shouldn't have even been electrocuted, his body would have simply punctured the switch and he'd be stuck.
 * 5) Pop should have died from electrocution, not decapitation.
 * 6) Lumpy shouldn't have been able to fall backwards in the closet.
