Simpson Safari

Maggie eats a magazine and Marge takes her to the hospital, leaving Homer to do the food shopping.  Homer abuses a bag boy, which leads to the bag boys going out on strike.  With them on strike, the family does not go grocery shopping.  When their food runs out, Homer searches the house for food and he finds 30+-year-old animal crackers.  When he opens the box, he finds it contains a golden giraffe; the token, which indicates the recipient, has won an African safari.  The manufacturer honors the prize and sends the Simpson family to Africa.  Their tour of the African wilderness is very strange.  A local tribe treats them to a concert.  Later, when a hippo tries to attack Homer, the Simpson family escapes on a makeshift raft.  They sail down river and end up having to fend for themselves in the wilderness.  They come across a scientist who is researching monkeys.  When poachers come to take the monkeys, the Simpson family helps him to fight back.  Lisa soon discovers that the researcher actually runs a chimp diamond mine and the poachers are actually Greenpeace.  The Simpsons fly back home.
