In the episode, Cartman, Kenny, Kyle and Stan send money to an African charity hoping to get a sports watch, but are instead sent an Ethiopian child whom they dub "Starvin' Marvin".
The mad scientist Dr. Mephesto tries to warn Mayor McDaniels that genetically engineered turkeys he had been breeding to feed to the poor have gone crazy and are now attacking humans.
Back at school, Mr. Garrison announces the food drive is a failure because students have brought in only a few cans of creamed corn.
Cartman, who had previously cared little for the impoverished in Africa, is unable to bear the lack of food and poor living conditions there; furthermore, he attempts to convince the Red Cross there that he's not one of the Africans, but fails.
The FBI returns Cartman to South Park and takes Marvin home, but not before he brings the bodies of the dead turkeys back to Ethiopia for everyone to eat.
Parker said he had always wondered how a starving African child would react if they were taken to a large buffet dinner at an American restaurant, with "people leaving tons of food on their plates",[1] which served as further inspiration for the episode.
[5] Psychologists Gilbert Reyes and Gerard Jacobs have cited "Starvin' Marvin" as one example of popular culture voicing criticisms of humanitarianism "as an overblown industry leeching off others' suffering and harming its purported beneficiaries".
[8] "Starvin' Marvin" explores and satirizes gluttony in the US, particularly through its unflattering portrayal of Sally Struthers, who gorges on donated food meant for starving children.
[9] The greed and wastefulness shown in the buffet scene, as well as Cartman's overall greediness and lack of understanding regarding the plight of starving African children, has been said to demonstrate an over-abundance and decadence typically associated with Americans.
Scott Calef, a philosophy professor who studies popular culture, said the destruction caused by the turkeys, despite the best of intentions by Dr. Mephesto, is indicative of the unpredictable nature and ethical ambiguity of the use of genetic engineering for the betterment of humankind.
The scenes in which Chef, and later the lead turkey, don blue and white war paint and speak inspirational words to their armies are a parody of Braveheart, the 1995 Mel Gibson-directed film about Scottish historical hero William Wallace.

[1] After the episode aired, Parker and Stone received feedback that audiences felt "Starvin' Marvin" was especially unkind to Struthers.
Although they did not speak to her themselves, the duo received word that Struthers was a fan of the show until "Starvin' Marvin" aired, after which she was very upset and reportedly reacted emotionally over her portrayal.
In a DVD commentary track, Parker said of Struthers, "Dude, you're really setting yourself up if you're going to be that fat and go on the air talking about [starving children].
"[1] Tom Carson, television critic for The Village Voice, praised the episode, which he said "featured some amazing sick jokes about American affluence and obliviousness".
