In Over Your Hedge is the fourteenth episode of Season 4 and the 92nd overall.
The episode begins with Flippy reading a book on a hammock in his backyard. While Flippy is quietly reading his book, his neighbor, Lumpy, is trying to start up his lawnmower, which creates noises that irritate Flippy. Flippy tells Lumpy to be more quiet so Lumpy apologizes and grabs a weed-whacker, which also makes noise as Lumpy tries to start it up. Flippy tells Lumpy to be quiet again and Lumpy nervously laughs as he grabs a pair of hedge shears. Lumpy looks at Flippy to see if it's okay with him, Flippy smiles back in approval and lies back down to read.
Lumpy starts cutting a bush with the shears, which turns out to be a very slow process. Lumpy gets an idea and combines his shears with the weed-whacker, creating motorized shears. As he starts up his invention with ease, his motorized shears start to billow, this results in smoke covering Flippy from his yard. As the smoke clears up, Flippy notices a fellow soldier who is wearing a gas mask, lying on the ground on a battlefield, reaching his hand to him. Flippy removes the gas mask from the soldier to reveal that war chemicals have melted his face, which causes Flippy to flip out.
As Lumpy finishes cutting the bush, a garden flamingo is thrown, almost hitting Lumpy. Lumpy turns around and sees Fliqpy running towards him with two garden flamingos in his hands. Fliqpy throws the garden flamingos at Lumpy, impaling his arms. Lumpy tries to run away, but Fliqpy spots the two flamingos that Lumpy is carrying from behind a fence. As Lumpy continues to run, Fliqpy uses a cord to slice off Lumpy's legs and the ends of the flamingos pin Lumpy to the ground as he falls.
Fliqpy jumps on Lumpy's back and tightens the cord around Lumpy's head, he then grabs the end of the cord and yanks on it several times, similar to how one starts up a lawnmower. As Fliqpy gives a final pull, Lumpy's head starts to spin and we see Lumpy's detached head float in the sky, while spinning like a helicopter.
The episode ends, when Flippy is seen happily cutting a bush with a weed-whacker, but as the camera zooms out, it is shown that at the end of the weed-whacker is Lumpy's head and his antler is being used as blades to cut the leaves off a bush forming a flamingo sculpture. As the Iris closes in on Flippy, Fliqpy starts laughing as episode ends.
