1 cup pineapple chunks or tidbits, well drained
1 cup mandarin oranges, well drained
1 cup shredded coconut
1 cup miniature marshmallows
1 cup sour cream
Combine all ingredients. Mix well (this step is really important because if you leave any sour cream hanging around the top of the bowl, it still tastes sour!).
Chill several hours or overnight (if possible, if not, just put it on the table and watch it disappear!).
