Chose one "Big Bad Wolf." Together everyone will choose a object to run around, say a tree, porch post. Frisbee, anything really.
The wolf steps out of hearing distance and counts to 50, 100, whatever. Everyone who is not the wolf picks a color and announces it to the group.
The wolf checks that the group is ready and comes back when the others have confirmed they are ready.
Big Bad Wolf: "Knock Knock!"
Others: "Who's There?"
Big Bad Wolf: "The Big Bad Wolf!"
Others: "What Do You Want?"
Big Bad Wolf: "Colored Eggs!"
Others: "What Color?"
The wolf will choose a color and if a person has that color, they will run around the chosen object and back to the groups base location. The wolf will try to tag the person.
When I researched this online, I found that some groups were taught the game with a group color. This would be chosen in the begining like the other colors. If it is called, everyone would run around the chosen object.
If someone is tagged, they are the new wolf. Otherwise, the wolf keeps choosing colors.
