BLESS THIS MESS
In a large bowl, add the pineapple, orange, and coconut.
Add the sour cream, and fold to combine.
Add the mini marshmallows, and fold to combine.
Refrigerate for 2 to 3 hours before serving.
You can eat this right away, but I like to let it sit a minute. The sour cream has time to get sweet that way, and I like the softer texture of the marshmallows.
