Angry Birds: Mutated Birds is a game where the pigs have invented the X-PIG formula and used it on the birds, mutating them into pigs. All except Bomb, who exploded after seeing the others mutated. It's up to the fanon birds! The birds, being exposed to the formula, are more vulnerable to being popped now, since the pigs are generally weak.
In a cutscene in episode 3, Aqua Vacuum Bird discovers the X-PIG's antidote is a mixture of salsa, honey, and ginger ale. In episode 5, Cecil Wilson catches and antidotes Orange Bird. In episode 7, Sam Sparks Bird catches and antidotes White Bird. Two more birds are antidoted: Hal and Terence. Then later, Samuel the Purple Bird antidotes Yellow Bird. Afterwards, all the birds antidote the rest of the flock and defeat the pigs. (Note: Do not add any more antidoted birds. There are already enough.)
