The Immunity Milk is a form of Immunity created by MePhone4 after Immunity Votes were taken away. Drinking the milk would grant the player instant immunity for the next elimination, but it can only be used once in Inanimate Insanity Invitational. Its first appearance is in "Friend or Froze".
In The Series[]
In Friend or Froze, Yin-Yang complains to MePhone after the immunity votes are taken away, due to him winning them 6 times in total. MePhone realizes that the removal of immunity votes made the game "boring", so he creates the Immunity Milk. MePhone says that if any contestant agrees that Yin-Yang should drink the milk, he would be allowed to drink it and be safe from the elimination. Yin-Yang tries to convince Cabby at first, but she secretly is against it, due to her believing it would seal her fate against the majority alliance. During the challenge however, Cabby realizes the advantages the milk can have and grants Yin-Yang permission to drink it. Before the elimination, Yin-Yang offers the milk to Cabby, forcing the Looney Balloonies to make a choice who to vote for, not knowing which one of the two would drink the milk during the vote. At the elimination, MePhone asks Yin-Yang whether he would drink the milk or not. Cabby convinces Yin-Yang that they would be fine, and he puts down the milk, saving it for another elimination.
In Spring on the Breakfast!, Yin-Yang decides to not use the milk, but manages to stay in the game due to a tiebreaker between him and Silver Spoon, keeping him in the game.
In Blue Buried, after watching Blueberry convince Nickel to vote Cabby along with him, Yin and Yang made the conscious decision to give the milk to Cabby. Cabby ended up drinking the milk, but this however sealed Yin-Yangs fate, with Blueberry's alliance actually voting for him, making him the 15th eliminated contestant. Yin-Yang takes his elimination well however, with it giving Yin and Yang both a personal victory.
