[Breakfast Cereal] What exactly happened that is preventing people from simply going to the store to buy cereal?

Did the economy collapse?  

Have all foodstuffs besides cereal disappeared?  

Are the kids chasing Lucky so they can eat, or for his magical powers?

Is the Trix Rabbit just a kleptomaniac, or is there something more to it?

Did the Cookie Bandit get arrested for his crimes (and that's why we don't see him anymore)?  Does that make cereal theft illegal to the point that we never see the criminals again once they're caught?

Cereal used to be abundant and available. But things went bad when Sonny went coo coo for cocoa puffs. He couldn't get enough. He alone consumed the cocoa puff plant to the point of extinction. He was lost for months in the rain forests of south america, eating the rare plant in it's raw (and most potent) form. When it was all gone, he emerged, and went beyond bonkers. He couldn't deal with withdrawal, so he moved onto froot loops... He slaughtered Toucan Sam and his nephews while they slumbered and ate the entire supply. Without his rainbow nose, froot loops were now gone. He moved onto others... the cheerios bee was an easy kill, count chocula offered a greater challenge, and so on and so forth he went. Sonny came home with a vengeance. Eventually, cracked out on a sugar high, and suffering from advanced stages of type 2 diabetes, the chocolate loving bird collapsed in a pile of self shame, feces and vomit. His reign of terror was over, but the wages of his war still lay upon us. Those few who are fortunate enough to have cereal are reluctant to share their part of a complete breakfast... especially with other anthropomorphic animals who are a little too crazy about the stuff. We all remember Sonny.

The pot of gold at the end of the rainbow is Lucky... if we can manage to catch him, and harness his powers, we should be able to once again return shitty bowls of carbs and sugar to the modern world. Those easily distracted children who chase him nonstop are heroes. One day, their efforts will be remembered.
