Vallery takes a tour of Mr. Wonka's Chocolate Factory, and when she finds out about his brand-new gum she can't resist! Before he can stop her, she's chewing away on the gum and starts to get to the first course, tomato soup! It's so delicious she doesn't listen to Wonka's warning and keeps going past the second course. Once that's over, it's time for desert and that's when things start to get interesting. Vallery starts to turn blue and blow up! She's becoming a BLUEBERRY! She panics at first not knowing if she is going to explode, or ever be her original size again. But soon she realizes just how good being a blueberry feels and starts to enjoy it....
