(The complete plot for this South Park Episode)
After seeing a commercial about starving children in Africa, Cartman, Stan, Kenny and Kyle send money to Sally Struthers' charity organization, the Christian Children's Fund. They do not care about the cause, but want the free sports watch that comes with the sponsorship. However, due to a miscommunication, an Ethiopian boy is delivered to the boys instead of the watch. Although initially shocked, the four boys befriend him, and Cartman names the boy Starvin' Marvin. Meanwhile, mobs of wild turkeys begin attacking and killing South Park residents. Mad scientist Dr. Mephisto 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. Mephisto is instead ignored and ridiculed by McDaniels.The boys take Marvin to an all-you-can-eat buffet, where he is shocked by how much food the townsfolk consume compared to his home country, and by how wasteful Cartman is with his food. Back at school, Mr. Garrison announces the food drive is a failure because students have brought in only a few cans of creamed corn. The boys present Marvin to the class during show and tell, after which Mr. Garrison and Principal Victoria tell the boys they will have to call Red Cross and send Marvin home. Meanwhile, Dr. Mephisto shows Chef that the turkey DNA is growing so rapidly that the turkeys might take over the world if they are not stopped.
The FBI arrives to take Marvin back to Ethiopia, but Marvin tricks them into taking Cartman instead. Cartman, who had previously cared little for the impoverished in Africa, is unable to bear the lack of food and poor living conditions there. While praying to God in Addis Ababa, Cartman says he is sorry he made fun of poor people. He eventually finds a Red Cross shack, where Sally Struthers is hoarding all the food meant for charity. After a brief fight, Cartman exposes all of Miss Struthers's hoarding of the food supply to the Ethiopians, who then take control of the food supply.
Back in South Park, Chef rallies the townspeople to fight the genetically engineered turkeys. A massive battle ensues in which Kenny is killed, but eventually the South Park residents kill all the turkeys and claim victory. 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.
