Beware of the Purple Peanut Butter

The reader will have to spend the summer with their aunt and uncle. That means that the reader will have to spend time with their cousins, Barney and Dora. During a game of hide-and-seek, the reader discovers a fridge in the basement. Inside the fridge, there is a slice of cake from a place called "Effy's Bakery" and a container filled with a purple substance. Strangely, the substance smells like peanut butter.

If the reader chooses to eat the Purple Peanut Butter, they will slowly start to shrink down every few minutes. There is never an explanation for where the Purple Peanut Butter came from.

"Goosebumps: The Game"
