Pig Prison

Cutscenes
Chuck has been freed by Red and Prince Porky  is very angry because of them but he still stands there to see how strong they are.

After Unlocking Chuck
In Waves 1 and 2, when you level up, more pigs are added (Example: Bird Catcher is added, Rogue is added, Stick Pig is added, Wealthy Rogue is added). Wave 3 is even more different than usual. You will have the same pigs as in the third Wave before unlocking Chuck, but without the cage. Sometimes, one Pig Guard will be shown, and two Stick Pigs will be added, or on rare occasion, no Ironclad Pig will be shown, leaving only the Stick Pigs, Pig Guard, and Rogue. There's more - a Wealthy Rogue will be popping up in which wave on rare occasion.

Before Unlocking Chuck
Attack one pig in Waves 1 and 2. Only destroy the cage in wave 3 to free Chuck. Chuck will kill all pigs.

After Unlocking Chuck
Same formula, but some pigs will be added or removed in Waves 1, 2 and 3 and Wave 3 will not have the cage. So you need to defeat those pigs yourself in Wave 3.
