Fat Friends

In this episode, Giggles and Petunia put on a lot of weight. This episode has been nicknamed "The Kinkiest Damn Episode of all Time," by fans because of how it contains a lot of fetish material.

Plot
Giggles and Petunia are taking a walk in the woods when all of a sudden, they see a sign that says "Big Rock Candy Mountain". They take a hike into where the sign is leading them and see candy everywhere. When then see a montage of Giggles and Petunia stuffing their faces with candy getting larger and larger by the minute. Then it cuts to Giggles and Petunia who have both ballooned up to ginormous porpotions. Petunia burps and it disgusts Giggles. Then they are shown in a montage rolling around, bumping bellies, and pretending to be sumo wrestlers with the song "Fat Bottomed Girls" by Queen playing. After that, Giggles noticing something is wrong with her stomach and throws up. Petunia throws up after seeing Giggles's vomit and then Giggles notices that she is about to explode. Giggles then barfs 5 more times and explodes in the most graphic way imaginable. Blood, guts, and her heart fly everywhere. Giggles's kidney even lands in Petunia's mouth and she barfs. Then Petunia accidentally rolls down a hill to her death and goes splat right on to the bottom of a cliff. She sees a sign that says,

"Cliff hanger. Cliche isn't it?" and Petunia rolls her eyes. She may have a lot of blood all over her but Petunia's still alive. Then all of a sudden, a monkey shows up and starts bouncing on Petunia's belly. Petunia doesn't like it and she bites the monkey's finger. The monkey then flips her off and starts mauling the crap out of her. He rips out Petunia's eyeballs, cuts out her heart with a chainsaw, rips out all her all internal organs all while screaming and finally ends it with flinging poop at her dead corpse. The monkey then looks at the camera and starts singing the theme song to The Monkees with a devious looking grin on his face. An elephant then appears out of nowhere and shits on the monkey and the elephant makes another evil gren. Then the credits start rolling.

Trivia
This might be the single most graphic and gross episode in recent seasons. The fact that it also features the middle finger, fetish content, and an elephant shitting on another animal in addition to the abnormallly grotesque violence gave this episode a TV-MA rating rather than the usual TV-14.
