Forum:Theory: Not canon at all.

My theory is the pigs are good guys. They are the protagonists. They want to help the birds using their machines saw in Bad Piggies. Everybody knows that farts are made of methane, and it can be used as fuel for their machines. Fried eggs make people fart more. Why wouldn't it be the same with pigs! The pigs ask the birds for the eggs. They say no. Then the pigs steal the eggs. The birds are angry and try to get them back.
