Here is what I believe.
I believe Vudu has been honest with us and that he was hit by two items NOT the Blue Shell on day one.
We know for fact one of those items was a banana. Could the other item have been the Blue Shell, yes, and that would mean he is on the RED team.
However, if he told the Truth then he is the Green Player. I had a coin stolen from me by the green player, this is fact...been confirm to me by Plugabugz in a PM...and confirmed by him to another person. So, Yesterday we had 2 people near death...and today only 1.
It is probable to believe that Vudu stole my item, fearing that I believed he was Red and would attack him again...only he just got a COIN. However, this coin would have been used to heal himself 1 point. Now, if nobody targetted Vudu for an attack he would not be near death.
If somebody did Target him, most likely the star that was activated was used to protect him. Either by the Red or Blue team not knowing who he really is. Or By Himself. The Green player gets two items. That would mean he was able to Heal Himself and evade attack...bringing himself away from near death. It would also mean attacks would not work on him even today...because Stars last 2 days if I remember correctly.
So if somebody used an Item against Vudu we would know if the Star was used on him or not...because he would be near death again with only 1 Point remaining...however, he most likely won't be near death because of this Star protection...which would help prove my theory.
