While the Simpsons are watching TV, Homer falls asleep while eating "Herschel's Smootches"-brand fudge balls. He starts dreaming about "The Land of Chocolate," a place made entirely of candy (mostly chocolate). After Homer looks at the discount chocolate, a White Chocolate Rabbit appears and informs him he is eating their world. Then he dares Homer to eat him. The rabbit escapes across a chocolate river, which Homer crosses by jumping on giant cakes and marshmallows. He encounters with a chocolate rabbit and eats it before destroying some chocolate stands.
Now he is in Fudgetown and follows a path between the houses while eating all of the rabbits he sees. He destroys the Marge fountains, the place where the rabbits come from. Later, he destroys a giant pretzel to reach a huge cake in the middle of a big chocolate lake. Homer presses a button to make some giant cookies appear and jump on them to get to the cake. He scales it and gets to the top to fight the White Chocolate Rabbit and eat it. When he does so, he gets the power of Homer Ball: he can turn into a giant ball and boost onto things. The cake disappears, revealing an underground part full of rabbits Homer boosts and eats.
After that, he wakes up angry because that was just a dream.
