The pig gives you an angry eye like you just ate the last donut, which you did because you need to put delicious things in your face at any given moment. It's a rare condition, but fortunately you can walk it off any time you go to Africa.

So, the last time you went to Africa you happened to see the Lion King and decided to try that thing where Pumba and Timon eat the bugs, making them seem all delectable. In reality, when you tried it your tongue turned purple and you spit soda out of your nose, which doesn't even make sense, but trust me, it was spectacularly gross.
