This challenge is called "Fill in the blank" and this is how it works:
On the forum I will post the name of a previous C&A Survivor tribe. However, I will leave an empty space.
Each individual player in the tribe will have a chance to respond with the missing character.

C*TABATO
Answer: O
The two tribes that score 4 points first, win immunity and are saved from the tribal council.
